"value": "AV:L - The vulnerable path is reached through `DRM_IOCTL_AMDGPU_CS`/`AMDGPU_GEM_CREATE` on the local `/dev/dri/renderD*` device node, requiring local system access. No network or adjacent-network reachability exists.\nAC:L - Triggering is a deterministic, race-free ioctl sequence \u2014 create a GTT BO, submit it as the CS user-fence BO, then release it \u2014 repeatable in a loop on any default amdgpu configuration. No conditions outside the attacker\u0027s control are involved.\nPR:L - Both required ioctls are `DRM_RENDER_ALLOW`, so any unprivileged user able to open the render node (standard for desktop sessions, `render`-group members, and GPU-enabled containers) can reach the code with no capabilities and without DRM master.\nUI:N - The attacking process performs the entire allocate/submit/free sequence itself; no victim action or interaction is needed.\nS:U - The stale mappings live in the GPU\u0027s own GART remap table and the affected resource is host kernel memory managed by the same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The GART retains valid entries to system pages that have been freed and recycled for arbitrary kernel and user data, so GPU reads of that aperture return reclaimed memory contents instead of faulting \u2014 a use-after-free class disclosure primitive into attacker-visible GPU buffers.\nI:H - The same stale entries are writable by the GPU, giving DMA writes into pages the kernel has reallocated for other purposes (kernel objects, page tables, other processes\u0027 data), which is arbitrary memory corruption bypassing CPU MMU protection.\nA:H - GPU DMA into reclaimed kernel pages corrupts live kernel structures leading to oops/panic, and on IOMMU-enabled systems the torn-down DMA mappings produce IO_PAGE_FAULT storms, GPU hangs, and device resets."

No conditions outside the attacker\u0027s control are involved.\nPR:L - Both required ioctls are `DRM_RENDER_ALLOW`, so any unprivileged user able to open the render node (standard for desktop sessions, `render`-group members, and GPU-enabled containers) can reach the code with no capabilities and without DRM master.\nUI:N - The attacking process performs the entire allocate/submit/free sequence itself; no victim action or interaction is needed.\nS:U - The stale mappings live in the GPU\u0027s own GART remap table and the affected resource is host kernel memory managed by the same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The GART retains valid entries to system pages that have been freed and recycled for arbitrary kernel and user data, so GPU reads of that aperture return reclaimed memory contents instead of faulting \u2014 a use-after-free class disclosure primitive into attacker-visible GPU buffers.\nI:H - The same stale entries are writable by the GPU, giving DMA writes into pages the kernel has reallocated for other purposes (kernel objects, page tables, other processes\u0027 data), which is arbitrary memory corruption bypassing CPU MMU protection.\nA:H - GPU DMA into reclaimed kernel pages corrupts live kernel structures leading to oops/panic, and on IOMMU-enabled systems the torn-down DMA mappings produce IO_PAGE_FAULT storms, GPU hangs, and device resets."

OESA-2024-1682 (CVE-2021-47421)
Vulnerability from osv_openeuler – Published: 2024-05-31 11:07 – Updated: 2026-08-06 11:07 – Source websiteThe Linux Kernel, the operating system core itself.
Security Fix(es):
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: handle the case of pci_channel_io_frozen only in amdgpu_pci_resume
In current code, when a PCI error state pci_channel_io_normal is detectd, it will report PCI_ERS_RESULT_CAN_RECOVER status to PCI driver, and PCI driver will continue the execution of PCI resume callback report_resume by pci_walk_bridge, and the callback will go into amdgpu_pci_resume finally, where write lock is releasd unconditionally without acquiring such lock first. In this case, a deadlock will happen when other threads start to acquire the read lock.
To fix this, add a member in amdgpu_device strucutre to cache pci_channel_state, and only continue the execution in amdgpu_pci_resume when it's pci_channel_io_frozen.(CVE-2021-47421)
In the Linux kernel, the following vulnerability has been resolved:
ptp: Fix possible memory leak in ptp_clock_register()
I got memory leak as follows when doing fault injection test:
unreferenced object 0xffff88800906c618 (size 8): comm "i2c-idt82p33931", pid 4421, jiffies 4294948083 (age 13.188s) hex dump (first 8 bytes): 70 74 70 30 00 00 00 00 ptp0.... backtrace: [<00000000312ed458>] __kmalloc_track_caller+0x19f/0x3a0 [<0000000079f6e2ff>] kvasprintf+0xb5/0x150 [<0000000026aae54f>] kvasprintf_const+0x60/0x190 [<00000000f323a5f7>] kobject_set_name_vargs+0x56/0x150 [<000000004e35abdd>] dev_set_name+0xc0/0x100 [<00000000f20cfe25>] ptp_clock_register+0x9f4/0xd30 [ptp] [<000000008bb9f0de>] idt82p33_probe.cold+0x8b6/0x1561 [ptp_idt82p33]
When posix_clock_register() returns an error, the name allocated in dev_set_name() will be leaked, the put_device() should be used to give up the device reference, then the name will be freed in kobject_cleanup() and other memory will be freed in ptp_clock_release().(CVE-2021-47455)
In the Linux kernel, the following vulnerability has been resolved:
net: enetc: deny offload of tc-based TSN features on VF interfaces
TSN features on the ENETC (taprio, cbs, gate, police) are configured through a mix of command BD ring messages and port registers: enetc_port_rd(), enetc_port_wr().
Port registers are a region of the ENETC memory map which are only accessible from the PCIe Physical Function. They are not accessible from the Virtual Functions.
Moreover, attempting to access these registers crashes the kernel:

Split enetc_setup_tc() into separate functions for the PF and for the VF drivers. Also remove enetc_qos.o from being included into enetc-vf.ko, since it serves absolutely no purpose there.(CVE-2022-48645)
In the Linux kernel, the following vulnerability has been resolved:
drm/tegra: dsi: Add missing check for of_find_device_by_node
Add check for the return value of of_find_device_by_node() and return the error if it fails in order to avoid NULL pointer dereference.(CVE-2023-52650)
In the Linux kernel, the following vulnerability has been resolved:
NTB: fix possible name leak in ntb_register_device()
If device_register() fails in ntb_register_device(), the device name allocated by dev_set_name() should be freed. As per the comment in device_register(), callers should use put_device() to give up the reference in the error path. So fix this by calling put_device() in the error path so that the name can be freed in kobject_cleanup().
As a result of this, put_device() in the error path of ntb_register_device() is removed and the actual error is returned.
In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: fix a memleak in gss_import_v2_context
The ctx->mech_used.data allocated by kmemdup is not freed in neither gss_import_v2_context nor it only caller gss_krb5_import_sec_context, which frees ctx on error.
Thus, this patch reform the last call of gss_import_v2_context to the gss_krb5_import_ctx_v2, preventing the memleak while keepping the return formation.(CVE-2023-52653)
In the Linux kernel, the following vulnerability has been resolved:
io_uring: drop any code related to SCM_RIGHTS
This is dead code after we dropped support for passing io_uring fds over SCM_RIGHTS, get rid of it.(CVE-2023-52656)
In the Linux kernel, the following vulnerability has been resolved:
net: atlantic: eliminate double free in error handling logic
Driver has a logic leak in ring data allocation/free, where aq_ring_free could be called multiple times on same ring, if system is under stress and got memory allocation error.
Ring pointer was used as an indicator of failure, but this is not correct since only ring data is allocated/deallocated. Ring itself is an array member.
Changing ring allocation functions to return error code directly. This simplifies error handling and eliminates aq_ring_free on higher layer.(CVE-2023-52664)
In the Linux kernel, the following vulnerability has been resolved:
ALSA: scarlett2: Add clamp() in scarlett2_mixer_ctl_put()
Ensure the value passed to scarlett2_mixer_ctl_put() is between 0 and SCARLETT2_MIXER_MAX_VALUE so we don't attempt to access outside scarlett2_mixer_values[].(CVE-2023-52674)
In the Linux kernel, the following vulnerability has been resolved:
ACPI: LPIT: Avoid u32 multiplication overflow
In lpit_update_residency() there is a possibility of overflow in multiplication, if tsc_khz is large enough (> UINT_MAX/1000).
Change multiplication to mul_u32_u32().
Found by Linux Verification Center (linuxtesting.org) with SVACE.(CVE-2023-52683)
In the Linux kernel, the following vulnerability has been resolved:
calipso: fix memory leak in netlbl_calipso_add_pass()
If IPv6 support is disabled at boot (ipv6.disable=1), the calipso_init() -> netlbl_calipso_ops_register() function isn't called, and the netlbl_calipso_ops_get() function always returns NULL. In this case, the netlbl_calipso_add_pass() function allocates memory for the doi_def variable but doesn't free it with the calipso_doi_free().

TIPC bearer-related names including link names must be null-terminated strings. If a link name which is not null-terminated is passed through netlink, strstr() and similar functions can cause buffer overrun. This causes the above issue.
This patch changes the nla_policy for bearer-related names from NLA_STRING to NLA_NUL_STRING. This resolves the issue by ensuring that only null-terminated strings are accepted as bearer-related names.
syzbot reported similar uninit-value issue related to bearer names [2]. The root cause of this issue is that a non-null-terminated bearer name was passed. This patch also resolved this issue.(CVE-2023-52845)

hsr: Prevent use after free in prp_create_tagged_frame()
The prp_fill_rct() function can fail. In that situation, it frees the skb and returns NULL. Meanwhile on the success path, it returns the original skb. So it's straight forward to fix bug by using the returned value.(CVE-2023-52846)
In the Linux kernel, the following vulnerability has been resolved:
media: bttv: fix use after free error due to btv->timeout timer
There may be some a race condition between timer function bttv_irq_timeout and bttv_remove. The timer is setup in probe and there is no timer_delete operation in remove function. When it hit kfree btv, the function might still be invoked, which will cause use after free bug.
This bug is found by static analysis, it may be false positive.
Fix it by adding del_timer_sync invoking to the remove function.

padata: Fix refcnt handling in padata_free_shell()
In a high-load arm64 environment, the pcrypt_aead01 test in LTP can lead to system UAF (Use-After-Free) issues. Due to the lengthy analysis of the pcrypt_aead01 function call, I'll describe the problem scenario using a simplified model:
Suppose there's a user of padata named user_function that adheres to
the padata requirement of calling padata_free_shell after serial()
has been invoked, as demonstrated in the following code:
struct request {
struct padata_priv padata;
struct completion *done;
};
void parallel(struct padata_priv *padata) {
do_something();
}
void serial(struct padata_priv *padata) {
struct request *request = container_of(padata,
struct request,
padata);
complete(request->done);
}
void user_function() {
DECLARE_COMPLETION(done)
padata->parallel = parallel;
padata->serial = serial;
padata_do_parallel();
wait_for_completion(&done);
padata_free_shell();
}
In the corresponding padata.c file, there's the following code:
static void padata_serial_worker(struct work_struct *serial_work) {
...
cnt = 0;
while (!list_empty(&local_list)) {
...
padata->serial(padata);
cnt++;
}
local_bh_enable();
if (refcount_sub_and_test(cnt, &pd->refcnt))
padata_free_pd(pd);
}
Because of the high system load and the accumulation of unexecuted
softirq at this moment, local_bh_enable() in padata takes longer
to execute than usual. Subsequently, when accessing pd->refcnt,
pd has already been released by padata_free_shell(), resulting
in a UAF issue with pd->refcnt.
The fix is straightforward: add refcount_dec_and_test before calling
padata_free_pd in padata_free_shell.(CVE-2023-52854)

The following can crash the kernel:
# cd /sys/kernel/tracing # echo 'p:sched schedule' > kprobe_events # exec 5>>events/kprobes/sched/enable # > kprobe_events # exec 5>&-
The above commands:
- Change directory to the tracefs directory
- Create a kprobe event (doesn't matter what one)
- Open bash file descriptor 5 on the enable file of the kprobe event
- Delete the kprobe event (removes the files too)
- Close the bash file descriptor 5
The above causes a crash!
BUG: kernel NULL pointer dereference, address: 0000000000000028 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: 0000 [#1] PREEMPT SMP PTI CPU: 6 PID: 877 Comm: bash Not tainted 6.5.0-rc4-test-00008-g2c6b6b1029d4-dirty #186 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.2-debian-1.16.2-1 04/01/2014 RIP: 0010:tracing_release_file_tr+0xc/0x50
What happens here is that the kprobe event creates a trace_event_file "file" descriptor that represents the file in tracefs to the event. It maintains state of the event (is it enabled for the given instance?). Opening the "enable" file gets a reference to the event "file" descriptor via the open file descriptor. When the kprobe event is deleted, the file is also deleted from the tracefs system which also frees the event "file" descriptor.
But as the tracefs file is still opened by user space, it will not be totally removed until the final dput() is called on it. But this is not true with the event "file" descriptor that is already freed. If the user does a write to or simply closes the file descriptor it will reference the event "file" descriptor that was just freed, causing a use-after-free bug.
To solve this, add a ref count to the event "file" descriptor as well as a new flag called "FREED". The "file" will not be freed until the last reference is released. But the FREE flag will be set when the event is removed to prevent any more modifications to that event from happening, even if there's still a reference to the event "file" descriptor.(CVE-2023-52879)
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: mark set as dead when unbinding anonymous set with timeout
While the rhashtable set gc runs asynchronously, a race allows it to collect elements from anonymous sets with timeouts while it is being released from the commit path.
Mingi Cho originally reported this issue in a different path in 6.1.x with a pipapo set with low timeouts which is not possible upstream since 7395dfacfff6 ("netfilter: nf_tables: use timestamp to check for set element timeout").
Fix this by setting on the dead flag for anonymous sets to skip async gc in this case.
According to 08e4c8c5919f ("netfilter: nf_tables: mark newset as dead on transaction abort"), Florian plans to accelerate abort path by releasing objects via workqueue, therefore, this sets on the dead flag for abort path too.(CVE-2024-26643)
In the Linux kernel, the following vulnerability has been resolved:
wireguard: netlink: access device through ctx instead of peer
The previous commit fixed a bug that led to a NULL peer->device being dereferenced. It's actually easier and faster performance-wise to instead get the device from ctx->wg. This semantically makes more sense too, since ctx->wg->peer_allowedips.seq is compared with ctx->allowedips_seq, basing them both in ctx. This also acts as a defence in depth provision against freed peers.(CVE-2024-26950)
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: prevent kernel bug at submit_bh_wbc()
Fix a bug where nilfs_get_block() returns a successful status when searching and inserting the specified block both fail inconsistently. If this inconsistent behavior is not due to a previously fixed bug, then an unexpected race is occurring, so return a temporary error -EAGAIN instead.
This prevents callers such as __block_write_begin_int() from requesting a read into a buffer that is not mapped, which would cause the BUG_ON check for the BH_Mapped flag in submit_bh_wbc() to fail.(CVE-2024-26955)

s390/zcrypt: fix reference counting on zcrypt card objects
Tests with hot-plugging crytpo cards on KVM guests with debug kernel build revealed an use after free for the load field of the struct zcrypt_card. The reason was an incorrect reference handling of the zcrypt card object which could lead to a free of the zcrypt card object while it was still in use.

This is because we're completing the nfs_direct_request twice in a row.
The source of this is when we have our commit requests to submit, we process them and send them off, and then in the completion path for the commit requests we have
if (nfs_commit_end(cinfo.mds)) nfs_direct_write_complete(dreq);
However since we're submitting asynchronous requests we sometimes have one that completes before we submit the next one, so we end up calling complete on the nfs_direct_request twice.
The only other place we use nfs_generic_commit_list() is in __nfs_commit_inode, which wraps this call in a
nfs_commit_begin(); nfs_commit_end();
Which is a common pattern for this style of completion handling, one that is also repeated in the direct code with get_dreq()/put_dreq() calls around where we process events as well as in the completion paths.
Fix this by using the same pattern for the commit requests.
Before with my 200 node rocksdb stress running this warning would pop every 10ish minutes. With my patch the stress test has been running for several hours without popping.(CVE-2024-26958)

ubifs: ubifs_symlink: Fix memleak of inode->i_link in error path
For error handling path in ubifs_symlink(), inode will be marked as bad first, then iput() is invoked. If inode->i_link is initialized by fscrypt_encrypt_symlink() in encryption scenario, inode->i_link won't be freed by callchain ubifs_free_inode -> fscrypt_free_inode in error handling path, because make_bad_inode() has changed 'inode->i_mode' as 'S_IFREG'.

Free inode->i_link before marking inode bad. Method 2 is picked, it has less influence, personally, I think.(CVE-2024-26972)

KVM: Always flush async #PF workqueue when vCPU is being destroyed
Always flush the per-vCPU async #PF workqueue when a vCPU is clearing its completion queue, e.g. when a VM and all its vCPUs is being destroyed. KVM must ensure that none of its workqueue callbacks is running when the last reference to the KVM module is put. Gifting a reference to the associated VM prevents the workqueue callback from dereferencing freed vCPU/VM memory, but does not prevent the KVM module from being unloaded before the callback completes.
Drop the misguided VM refcount gifting, as calling kvm_put_kvm() from async_pf_execute() if kvm_put_kvm() flushes the async #PF workqueue will result in deadlock. async_pf_execute() can't return until kvm_put_kvm() finishes, and kvm_put_kvm() can't return until async_pf_execute() finishes:

If kvm_clear_async_pf_completion_queue() actually flushes the workqueue, then there's no need to gift async_pf_execute() a reference because all invocations of async_pf_execute() will be forced to complete before the vCPU and its VM are destroyed/freed. And that in turn fixes the module unloading bug as __fput() won't do module_put() on the last vCPU reference until the vCPU has been freed, e.g. if closing the vCPU file also puts the last reference to the KVM module.
Note that kvm_check_async_pf_completion() may also take the work item off the completion queue and so also needs to flush the work queue, as the work will not be seen by kvm_clear_async_pf_completion_queue(). Waiting on the workqueue could theoretically delay a vCPU due to waiting for the work to complete, but that's a very, very small chance, and likely a very small delay. kvm_arch_async_page_present_queued() unconditionally makes a new request, i.e. will effectively delay entering the guest, so the remaining work is really just:
trace_kvm_async_pf_completed(addr, cr2_or_gpa);
__kvm_vcpu_wake_up(vcpu);
mmput(mm);
and mmput() can't drop the last reference to the page tables if the vCPU is still alive, i.e. the vCPU won't get stuck tearing down page tables.
Add a helper to do the flushing, specifically to deal with "wakeup all" work items, as they aren't actually work items, i.e. are never placed in a workqueue. Trying to flush a bogus workqueue entry rightly makes __flush_work() complain (kudos to whoever added that sanity check).

In the Linux kernel, the following vulnerability has been resolved:
Squashfs: check the inode number is not the invalid value of zero
Syskiller has produced an out of bounds access in fill_meta_index().
That out of bounds access is ultimately caused because the inode has an inode number with the invalid value of zero, which was not checked.
The reason this causes the out of bounds access is due to following sequence of events:
-
Fill_meta_index() is called to allocate (via empty_meta_index()) and fill a metadata index. It however suffers a data read error and aborts, invalidating the newly returned empty metadata index. It does this by setting the inode number of the index to zero, which means unused (zero is not a valid inode number).
-
When fill_meta_index() is subsequently called again on another read operation, locate_meta_index() returns the previous index because it matches the inode number of 0. Because this index has been returned it is expected to have been filled, and because it hasn't been, an out of bounds access is performed.
This patch adds a sanity check which checks that the inode number is not zero when the inode is created and returns -EINVAL if it is.

fs: sysfs: Fix reference leak in sysfs_break_active_protection()
The sysfs_break_active_protection() routine has an obvious reference leak in its error path. If the call to kernfs_find_and_get() fails then kn will be NULL, so the companion sysfs_unbreak_active_protection() routine won't get called (and would only cause an access violation by trying to dereference kn->parent if it was called). As a result, the reference to kobj acquired at the start of the function will never be released.
Fix the leak by adding an explicit kobject_put() call when kn is NULL.(CVE-2024-26993)

serial/pmac_zilog: Remove flawed mitigation for rx irq flood
The mitigation was intended to stop the irq completely. That may be better than a hard lock-up but it turns out that you get a crash anyway if you're using pmac_zilog as a serial console:
ttyPZ0: pmz: rx irq flood ! BUG: spinlock recursion on CPU#0, swapper/0
That's because the pr_err() call in pmz_receive_chars() results in pmz_console_write() attempting to lock a spinlock already locked in pmz_interrupt(). With CONFIG_DEBUG_SPINLOCK=y, this produces a fatal BUG splat. The spinlock in question is the one in struct uart_port.
Even when it's not fatal, the serial port rx function ceases to work. Also, the iteration limit doesn't play nicely with QEMU, as can be seen in the bug report linked below.
A web search for other reports of the error message "pmz: rx irq flood" didn't produce anything. So I don't think this code is needed any more. Remove it.(CVE-2024-26999)

In the Linux kernel, the following vulnerability has been resolved:
USB: usb-storage: Prevent divide-by-0 error in isd200_ata_command
The isd200 sub-driver in usb-storage uses the HEADS and SECTORS values in the ATA ID information to calculate cylinder and head values when creating a CDB for READ or WRITE commands. The calculation involves division and modulus operations, which will cause a crash if either of these values is 0. While this never happens with a genuine device, it could happen with a flawed or subversive emulation, as reported by the syzbot fuzzer.
Protect against this possibility by refusing to bind to the device if either the ATA_ID_HEADS or ATA_ID_SECTORS value in the device's ID information is 0. This requires isd200_Initialization() to return a negative error code when initialization fails; currently it always returns 0 (even when there is an error).(CVE-2024-27059)

Using the combo of d_drop()/dput() (as mentioned in Documentation/filesystems/vfs.rst) isn't the right approach here, and leads to the reference counting problem seen above. Use d_invalidate() and update the code to not bother checking for error codes that can never happen.

In the Linux kernel, the following vulnerability has been resolved: x86/fpu: Keep xfd_state in sync with MSR_IA32_XFD Commit 672365477ae8 ("x86/fpu: Update XFD state where required") and commit 8bf26758ca96 ("x86/fpu: Add XFD state to fpstate") introduced a per CPU variable xfd_state to keep the MSR_IA32_XFD value cached, in order to avoid unnecessary writes to the MSR. On CPU hotplug MSR_IA32_XFD is reset to the init_fpstate.xfd, which wipes out any stale state. But the per CPU cached xfd value is not reset, which brings them out of sync. As a consequence a subsequent xfd_update_state() might fail to update the MSR which in turn can result in XRSTOR raising a #NM in kernel space, which crashes the kernel. To fix this, introduce xfd_set_state() to write xfd_state together with MSR_IA32_XFD, and use it in all places that set MSR_IA32_XFD.(CVE-2024-35801)

The first kiocb_set_cancel_fn() argument may point at a struct kiocb that is not embedded inside struct aio_kiocb. With the current code, depending on the compiler, the req->ki_ctx read happens either before the IOCB_AIO_RW test or after that test. Move the req->ki_ctx read such that it is guaranteed that the IOCB_AIO_RW test happens first.(CVE-2024-35815)

LoongArch: Define the __io_aw() hook as mmiowb()
Commit fb24ea52f78e0d595852e ("drivers: Remove explicit invocations of mmiowb()") remove all mmiowb() in drivers, but it says:
"NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation."
The mmio in radeon_ring_commit() is protected by a mutex rather than a spinlock, but in the mutex fastpath it behaves similar to spinlock. We can add mmiowb() calls in the radeon driver but the maintainer says he doesn't like such a workaround, and radeon is not the only example of mutex protected mmio.
So we should extend the mmiowb tracking system from spinlock to mutex, and maybe other locking primitives. This is not easy and error prone, so we solve it in the architectural code, by simply defining the __io_aw() hook as mmiowb(). And we no longer need to override queued_spin_unlock() so use the generic definition.
Without this, we get such an error when run 'glxgears' on weak ordering architectures such as LoongArch:

In the Linux kernel, the following vulnerability has been resolved:
netfilter: bridge: replace physindev with physinif in nf_bridge_info
An skb can be added to a neigh->arp_queue while waiting for an arp reply. Where original skb's skb->dev can be different to neigh's neigh->dev. For instance in case of bridging dnated skb from one veth to another, the skb would be added to a neigh->arp_queue of the bridge.
As skb->dev can be reset back to nf_bridge->physindev and used, and as there is no explicit mechanism that prevents this physindev from been freed under us (for instance neigh_flush_dev doesn't cleanup skbs from different device's neigh queue) we can crash on e.g. this stack:
arp_process neigh_update skb = __skb_dequeue(&neigh->arp_queue) neigh_resolve_output(..., skb) ... br_nf_dev_xmit br_nf_pre_routing_finish_bridge_slow skb->dev = nf_bridge->physindev br_handle_frame_finish
Let's use plain ifindex instead of net_device link. To peek into the original net_device we will use dev_get_by_index_rcu(). Thus either we get device and are safe to use it or we don't get it and drop skb.(CVE-2024-35839)

This is because the file has only one direct_node. After returning to -ENOSPC, reserved_blocks += ret will not be executed. As a result, the reserved_blocks at this time is still 0, which is not the real number of reserved blocks. Therefore, fsck cannot be set to repair the file.
After this patch, the fsck flag will be set to fix this problem.

ipv6: Fix infinite recursion in fib6_dump_done().
syzkaller reported infinite recursive calls of fib6_dump_done() during netlink socket destruction. [1]
From the log, syzkaller sent an AF_UNSPEC RTM_GETROUTE message, and then the response was generated. The following recvmmsg() resumed the dump for IPv6, but the first call of inet6_dump_fib() failed at kzalloc() due to the fault injection. [0]
12:01:34 executing program 3: r0 = socket$nl_route(0x10, 0x3, 0x0) sendmsg$nl_route(r0, ... snip ...) recvmmsg(r0, ... snip ...) (fail_nth: 8)
Here, fib6_dump_done() was set to nlk_sk(sk)->cb.done, and the next call of inet6_dump_fib() set it to nlk_sk(sk)->cb.args[3]. syzkaller stopped receiving the response halfway through, and finally netlink_sock_destruct() called nlk_sk(sk)->cb.done().
fib6_dump_done() calls fib6_dump_end() and nlk_sk(sk)->cb.done() if it is still not NULL. fib6_dump_end() rewrites nlk_sk(sk)->cb.done() by nlk_sk(sk)->cb.args[3], but it has the same function, not NULL, calling itself recursively and hitting the stack guard page.
To avoid the issue, let's set the destructor after kzalloc().

In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: discard table flag update with pending basechain deletion
Hook unregistration is deferred to the commit phase, same occurs with hook updates triggered by the table dormant flag. When both commands are combined, this results in deleting a basechain while leaving its hook still registered in the core.(CVE-2024-35897)
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: Fix potential data-race in __nft_flowtable_type_get()
nft_unregister_flowtable_type() within nf_flow_inet_module_exit() can concurrent with __nft_flowtable_type_get() within nf_tables_newflowtable(). And thhere is not any protection when iterate over nf_tables_flowtables list in __nft_flowtable_type_get(). Therefore, there is pertential data-race of nf_tables_flowtables list entry.
Use list_for_each_entry_rcu() to iterate over nf_tables_flowtables list in __nft_flowtable_type_get(), and use rcu_read_lock() in the caller nft_flowtable_type_get() to protect the entire type query process.(CVE-2024-35898)
In the Linux kernel, the following vulnerability has been resolved:
fbmon: prevent division by zero in fb_videomode_from_videomode()
The expression htotal * vtotal can have a zero value on overflow. It is necessary to prevent division by zero like in fb_var_to_videomode().

In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix possible memory leak in lpfc_rcv_padisc()
The call to lpfc_sli4_resume_rpi() in lpfc_rcv_padisc() may return an unsuccessful status. In such cases, the elsiocb is not issued, the completion is not called, and thus the elsiocb resource is leaked.
Check return value after calling lpfc_sli4_resume_rpi() and conditionally release the elsiocb resource.(CVE-2024-35930)
In the Linux kernel, the following vulnerability has been resolved:
btrfs: handle chunk tree lookup error in btrfs_relocate_sys_chunks()
The unhandled case in btrfs_relocate_sys_chunks() loop is a corruption, as it could be caused only by two impossible conditions:
-
at first the search key is set up to look for a chunk tree item, with offset -1, this is an inexact search and the key->offset will contain the correct offset upon a successful search, a valid chunk tree item cannot have an offset -1
-
after first successful search, the found_key corresponds to a chunk item, the offset is decremented by 1 before the next loop, it's impossible to find a chunk item there due to alignment and size constraints(CVE-2024-35936)
In the Linux kernel, the following vulnerability has been resolved:
pstore/zone: Add a null pointer check to the psz_kmsg_read
kasprintf() returns a pointer to dynamically allocated memory which can be NULL upon failure. Ensure the allocation was successful by checking the pointer validity.(CVE-2024-35940)

ACPI: CPPC: Use access_width over bit_width for system memory accesses
To align with ACPI 6.3+, since bit_width can be any 8-bit value, it cannot be depended on to be always on a clean 8b boundary. This was uncovered on the Cobalt 100 platform.

Instead, use access_width to determine the size and use the offset and width to shift and mask the bits to read/write out. Make sure to add a check for system memory since pcc redefines the access_width to subspace id.
If access_width is not set, then fall back to using bit_width.

In the Linux kernel, the following vulnerability has been resolved:
HID: i2c-hid: remove I2C_HID_READ_PENDING flag to prevent lock-up
The flag I2C_HID_READ_PENDING is used to serialize I2C operations. However, this is not necessary, because I2C core already has its own locking for that.
More importantly, this flag can cause a lock-up: if the flag is set in i2c_hid_xfer() and an interrupt happens, the interrupt handler (i2c_hid_irq) will check this flag and return immediately without doing anything, then the interrupt handler will be invoked again in an infinite loop.
Since interrupt handler is an RT task, it takes over the CPU and the flag-clearing task never gets scheduled, thus we have a lock-up.
Delete this unnecessary flag.(CVE-2024-35997)

Fix by returning if the lists are empty as there is nothing to migrate in this case.

Due to the lengthy analysis of\nthe pcrypt_aead01 function call, I\u0026apos;ll describe the problem scenario\nusing a simplified model:\r\n\r\nSuppose there\u0026apos;s a user of padata named `user_function` that adheres to\nthe padata requirement of calling `padata_free_shell` after `serial()`\nhas been invoked, as demonstrated in the following code:\r\n\r\n```c\nstruct request {\n struct padata_priv padata;\n struct completion *done;\n};\r\n\r\nvoid parallel(struct padata_priv *padata) {\n do_something();\n}\r\n\r\nvoid serial(struct padata_priv *padata) {\n struct request *request = container_of(padata,\n \t\t\t\tstruct request,\n\t\t\t\tpadata);\n complete(request-\u0026gt;done);\n}\r\n\r\nvoid user_function() {\n DECLARE_COMPLETION(done)\n padata-\u0026gt;parallel = parallel;\n padata-\u0026gt;serial = serial;\n padata_do_parallel();\n wait_for_completion(\u0026amp;done);\n padata_free_shell();\n}\n```\r\n\r\nIn the corresponding padata.c file, there\u0026apos;s the following code:\r\n\r\n```c\nstatic void padata_serial_worker(struct work_struct *serial_work) {\n ...\n cnt = 0;\r\n\r\n while (!list_empty(\u0026amp;local_list)) {\n ...\n padata-\u0026gt;serial(padata);\n cnt++;\n }\r\n\r\n local_bh_enable();\r\n\r\n if (refcount_sub_and_test(cnt, \u0026amp;pd-\u0026gt;refcnt))\n padata_free_pd(pd);\n}\n```\r\n\r\nBecause of the high system load and the accumulation of unexecuted\nsoftirq at this moment, `local_bh_enable()` in padata takes longer\nto execute than usual. Subsequently, when accessing `pd-\u0026gt;refcnt`,\n`pd` has already been released by `padata_free_shell()`, resulting\nin a UAF issue with `pd-\u0026gt;refcnt`.\r\n\r\nThe fix is straightforward: add `refcount_dec_and_test` before calling\n`padata_free_pd` in `padata_free_shell`.(CVE-2023-52854)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nclk: mediatek: clk-mt7629: Add check for mtk_alloc_clk_data\r\n\r\nAdd the check for the return value of mtk_alloc_clk_data() in order to\navoid NULL pointer dereference.(CVE-2023-52858)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nhwmon: (axi-fan-control) Fix possible NULL pointer dereference\r\n\r\naxi_fan_control_irq_handler(), dependent on the private\naxi_fan_control_data structure, might be called before the hwmon\ndevice is registered.

Trying to flush a bogus workqueue entry rightly makes\n__flush_work() complain (kudos to whoever added that sanity check).\r\n\r\nNote, commit 5f6de5cbebee (\u0026quot;KVM: Prevent module exit until al\n---truncated---(CVE-2024-26976)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nSquashfs: check the inode number is not the invalid value of zero\r\n\r\nSyskiller has produced an out of bounds access in fill_meta_index().\r\n\r\nThat out of bounds access is ultimately caused because the inode\nhas an inode number with the invalid value of zero, which was not checked.\r\n\r\nThe reason this causes the out of bounds access is due to following\nsequence of events:\r\n\r\n1. Fill_meta_index() is called to allocate (via empty_meta_index())\n and fill a metadata index. It however suffers a data read error\n and aborts, invalidating the newly returned empty metadata index.\n It does this by setting the inode number of the index to zero,\n which means unused (zero is not a valid inode number).\r\n\r\n2. When fill_meta_index() is subsequently called again on another\n read operation, locate_meta_index() returns the previous index\n because it matches the inode number of 0. Because this index\n has been returned it is expected to have been filled, and because\n it hasn\u0026apos;t been, an out of bounds access is performed.\r\n\r\nThis patch adds a sanity check which checks that the inode number\nis not zero when the inode is created and returns -EINVAL if it is.\r\n\r\n[phillip@squashfs.org.uk: whitespace fix]\n Link: https://lkml.kernel.org/r/20240409204723.446925-1-phillip@squashfs.org.uk(CVE-2024-26982)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nfs: sysfs: Fix reference leak in sysfs_break_active_protection()\r\n\r\nThe sysfs_break_active_protection() routine has an obvious reference\nleak in its error path.

However, pairing each mmiowb() removal in this patch with\nthe corresponding call to spin_unlock() is not at all trivial, so there\nis a small chance that this change may regress any drivers incorrectly\nrelying on mmiowb() to order MMIO writes between CPUs using lock-free\nsynchronisation.\u0026quot;\r\n\r\nThe mmio in radeon_ring_commit() is protected by a mutex rather than a\nspinlock, but in the mutex fastpath it behaves similar to spinlock.

OESA-2024-1768 (CVE-2021-47381)
Vulnerability from osv_openeuler – Published: 2024-06-28 11:07 – Updated: 2026-08-06 11:07 – Source websiteThe Linux Kernel, the operating system core itself.
Security Fix(es):
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: Fix DSP oops stack dump output contents
Fix @buf arg given to hex_dump_to_buffer() and stack address used in dump error output.(CVE-2021-47381)
In the Linux kernel, the following vulnerability has been resolved:
scsi: iscsi: Fix iscsi_task use after free
Commit d39df158518c ("scsi: iscsi: Have abort handler get ref to conn") added iscsi_get_conn()/iscsi_put_conn() calls during abort handling but then also changed the handling of the case where we detect an already completed task where we now end up doing a goto to the common put/cleanup code. This results in a iscsi_task use after free, because the common cleanup code will do a put on the iscsi_task.
This reverts the goto and moves the iscsi_get_conn() to after we've checked if the iscsi_task is valid.(CVE-2021-47427)
In the Linux kernel, the following vulnerability has been resolved:
spi: Fix deadlock when adding SPI controllers on SPI buses
Currently we have a global spi_add_lock which we take when adding new devices so that we can check that we're not trying to reuse a chip select that's already controlled. This means that if the SPI device is itself a SPI controller and triggers the instantiation of further SPI devices we trigger a deadlock as we try to register and instantiate those devices while in the process of doing so for the parent controller and hence already holding the global spi_add_lock. Since we only care about concurrency within a single SPI bus move the lock to be per controller, avoiding the deadlock.
This can be easily triggered in the case of spi-mux.(CVE-2021-47469)
(CVE-2023-39180)
In the Linux kernel, the following vulnerability has been resolved:
powerpc/powernv: Add a null pointer check in opal_powercap_init()
kasprintf() returns a pointer to dynamically allocated memory which can be NULL upon failure.(CVE-2023-52696)
In the Linux kernel, the following vulnerability has been resolved:
i2c: core: Run atomic i2c xfer when !preemptible
Since bae1d3a05a8b, i2c transfers are non-atomic if preemption is disabled. However, non-atomic i2c transfers require preemption (e.g. in wait_for_completion() while waiting for the DMA).
panic() calls preempt_disable_notrace() before calling emergency_restart(). Therefore, if an i2c device is used for the restart, the xfer should be atomic. This avoids warnings like:
[ 12.667612] WARNING: CPU: 1 PID: 1 at kernel/rcu/tree_plugin.h:318 rcu_note_context_switch+0x33c/0x6b0 [ 12.676926] Voluntary context switch within RCU read-side critical section! ...

[ 12.994527] atomic_notifier_call_chain from machine_restart+0x34/0x58 [ 13.001050] machine_restart from panic+0x2a8/0x32c
Use !preemptible() instead, which is basically the same check as pre-v5.2.(CVE-2023-52791)
In the Linux kernel, the following vulnerability has been resolved:
hid: cp2112: Fix duplicate workqueue initialization
Previously the cp2112 driver called INIT_DELAYED_WORK within cp2112_gpio_irq_startup, resulting in duplicate initilizations of the workqueue on subsequent IRQ startups following an initial request. This resulted in a warning in set_work_data in workqueue.c, as well as a rare NULL dereference within process_one_work in workqueue.c.
Initialize the workqueue within _probe instead.(CVE-2023-52853)
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix UAF issue in ksmbd_tcp_new_connection()
The race is between the handling of a new TCP connection and
its disconnection. It leads to UAF on struct tcp_transport in
ksmbd_tcp_new_connection() function.(CVE-2024-26592)
In the Linux kernel, the following vulnerability has been resolved:
net/ipv6: avoid possible UAF in ip6_route_mpath_notify()
syzbot found another use-after-free in ip6_route_mpath_notify() [1]
Commit f7225172f25a ("net/ipv6: prevent use after free in ip6_route_mpath_notify") was not able to fix the root cause.
We need to defer the fib6_info_release() calls after ip6_route_mpath_notify(), in the cleanup phase.

In the Linux kernel, the following vulnerability has been resolved:
inet: inet_defrag: prevent sk release while still in use
ip_local_out() and other functions can pass skb->sk as function argument.
If the skb is a fragment and reassembly happens before such function call returns, the sk must not be released.
This affects skb fragments reassembled via netfilter or similar modules, e.g. openvswitch or ct_act.c, when run as part of tx pipeline.
Eric Dumazet made an initial analysis of this bug. Quoting Eric: Calling ip_defrag() in output path is also implying skb_orphan(), which is buggy because output path relies on sk not disappearing.
A relevant old patch about the issue was : 8282f27449bf ("inet: frag: Always orphan skbs inside ip_defrag()")
[..]
net/ipv4/ip_output.c depends on skb->sk being set, and probably to an inet socket, not an arbitrary one.
If we orphan the packet in ipvlan, then downstream things like FQ packet scheduler will not work properly.
We need to change ip_defrag() to only use skb_orphan() when really needed, ie whenever frag_list is going to be used.
Eric suggested to stash sk in fragment queue and made an initial patch. However there is a problem with this:
If skb is refragmented again right after, ip_do_fragment() will copy head->sk to the new fragments, and sets up destructor to sock_wfree. IOW, we have no choice but to fix up sk_wmem accouting to reflect the fully reassembled skb, else wmem will underflow.
This change moves the orphan down into the core, to last possible moment. As ip_defrag_offset is aliased with sk_buff->sk member, we must move the offset into the FRAG_CB, else skb->sk gets clobbered.
This allows to delay the orphaning long enough to learn if the skb has to be queued or if the skb is completing the reasm queue.
In the former case, things work as before, skb is orphaned. This is safe because skb gets queued/stolen and won't continue past reasm engine.
In the latter case, we will steal the skb->sk reference, reattach it to the head skb, and fix up wmem accouting when inet_frag inflates truesize.(CVE-2024-26921)
In the Linux kernel, the following vulnerability has been resolved:
scsi: core: Fix unremoved procfs host directory regression
Commit fc663711b944 ("scsi: core: Remove the /proc/scsi/${proc_name} directory earlier") fixed a bug related to modules loading/unloading, by adding a call to scsi_proc_hostdir_rm() on scsi_remove_host(). But that led to a potential duplicate call to the hostdir_rm() routine, since it's also called from scsi_host_dev_release(). That triggered a regression report, which was then fixed by commit be03df3d4bfe ("scsi: core: Fix a procfs host directory removal regression"). The fix just dropped the hostdir_rm() call from dev_release().
But it happens that this proc directory is created on scsi_host_alloc(), and that function "pairs" with scsi_host_dev_release(), while scsi_remove_host() pairs with scsi_add_host(). In other words, it seems the reason for removing the proc directory on dev_release() was meant to cover cases in which a SCSI host structure was allocated, but the call to scsi_add_host() didn't happen. And that pattern happens to exist in some error paths, for example.
Syzkaller causes that by using USB raw gadget device, error'ing on usb-storage driver, at usb_stor_probe2(). By checking that path, we can see that the BadDevice label leads to a scsi_host_put() after a SCSI host allocation, but there's no call to scsi_add_host() in such path. That leads to messages like this in dmesg (and a leak of the SCSI host proc structure):
usb-storage 4-1:87.51: USB Mass Storage device detected proc_dir_entry 'scsi/usb-storage' already registered WARNING: CPU: 1 PID: 3519 at fs/proc/generic.c:377 proc_register+0x347/0x4e0 fs/proc/generic.c:376
The proper fix seems to still call scsi_proc_hostdir_rm() on dev_release(), but guard that with the state check for SHOST_CREATED; there is even a comment in scsi_host_dev_release() detailing that: such conditional is meant for cases where the SCSI host was allocated but there was no calls to {add,remove}_host(), like the usb-storage case.
This is what we propose here and with that, the error path of usb-storage does not trigger the warning anymore.(CVE-2024-26935)
In the Linux kernel, the following vulnerability has been resolved:
init/main.c: Fix potential static_command_line memory overflow
We allocate memory of size 'xlen + strlen(boot_command_line) + 1' for static_command_line, but the strings copied into static_command_line are extra_command_line and command_line, rather than extra_command_line and boot_command_line.
When strlen(command_line) > strlen(boot_command_line), static_command_line will overflow.
This patch just recovers strlen(command_line) which was miss-consolidated with strlen(boot_command_line) in the commit f5c7310ac73e ("init/main: add checks for the return value of memblock_alloc*()")(CVE-2024-26988)
In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix to avoid potential panic during recovery
During recovery, if FAULT_BLOCK is on, it is possible that f2fs_reserve_new_block() will return -ENOSPC during recovery, then it may trigger panic.
Also, if fault injection rate is 1 and only FAULT_BLOCK fault type is on, it may encounter deadloop in loop of block reservation.
Let's change as below to fix these issues: - remove bug_on() to avoid panic. - limit the loop count of block reservation to avoid potential deadloop.(CVE-2024-27032)
In the Linux kernel, the following vulnerability has been resolved:
clk: Fix clk_core_get NULL dereference
It is possible for clk_core_get to dereference a NULL in the following sequence:
clk_core_get() of_clk_get_hw_from_clkspec() __of_clk_get_hw_from_provider() __clk_get_hw()
__clk_get_hw() can return NULL which is dereferenced by clk_core_get() at hw->core.
Prior to commit dde4eff47c82 ("clk: Look for parents with clkdev based clk_lookups") the check IS_ERR_OR_NULL() was performed which would have caught the NULL.
Reading the description of this function it talks about returning NULL but that cannot be so at the moment.
Update the function to check for hw before dereferencing it and return NULL if hw is NULL.(CVE-2024-27038)
In the Linux kernel, the following vulnerability has been resolved:
net: phy: fix phy_get_internal_delay accessing an empty array
The phy_get_internal_delay function could try to access to an empty array in the case that the driver is calling phy_get_internal_delay without defining delay_values and rx-internal-delay-ps or tx-internal-delay-ps is defined to 0 in the device-tree. This will lead to "unable to handle kernel NULL pointer dereference at virtual address 0". To avoid this kernel oops, the test should be delay >= 0. As there is already delay < 0 test just before, the test could only be size == 0.(CVE-2024-27047)

genirq/cpuhotplug, x86/vector: Prevent vector leak during CPU offline
The absence of IRQD_MOVE_PCNTXT prevents immediate effectiveness of interrupt affinity reconfiguration via procfs. Instead, the change is deferred until the next instance of the interrupt being triggered on the original CPU.
When the interrupt next triggers on the original CPU, the new affinity is enforced within __irq_move_irq(). A vector is allocated from the new CPU, but the old vector on the original CPU remains and is not immediately reclaimed. Instead, apicd->move_in_progress is flagged, and the reclaiming process is delayed until the next trigger of the interrupt on the new CPU.
Upon the subsequent triggering of the interrupt on the new CPU, irq_complete_move() adds a task to the old CPU's vector_cleanup list if it remains online. Subsequently, the timer on the old CPU iterates over its vector_cleanup list, reclaiming old vectors.
However, a rare scenario arises if the old CPU is outgoing before the interrupt triggers again on the new CPU.
In that case irq_force_complete_move() is not invoked on the outgoing CPU to reclaim the old apicd->prev_vector because the interrupt isn't currently affine to the outgoing CPU, and irq_needs_fixup() returns false. Even though __vector_schedule_cleanup() is later called on the new CPU, it doesn't reclaim apicd->prev_vector; instead, it simply resets both apicd->move_in_progress and apicd->prev_vector to 0.
As a result, the vector remains unreclaimed in vector_matrix, leading to a CPU vector leak.
To address this issue, move the invocation of irq_force_complete_move() before the irq_needs_fixup() call to reclaim apicd->prev_vector, if the interrupt is currently or used to be affine to the outgoing CPU.
Additionally, reclaim the vector in __vector_schedule_cleanup() as well, following a warning message, although theoretically it should never see apicd->move_in_progress with apicd->prev_cpu pointing to an offline CPU.(CVE-2024-31076)
In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: Fix use-after-free bug in brcmf_cfg80211_detach
This is the candidate patch of CVE-2023-47233 : https://nvd.nist.gov/vuln/detail/CVE-2023-47233
In brcm80211 driver,it starts with the following invoking chain to start init a timeout worker:
->brcmf_usb_probe ->brcmf_usb_probe_cb ->brcmf_attach ->brcmf_bus_started ->brcmf_cfg80211_attach ->wl_init_priv ->brcmf_init_escan ->INIT_WORK(&cfg->escan_timeout_work, brcmf_cfg80211_escan_timeout_worker);
If we disconnect the USB by hotplug, it will call brcmf_usb_disconnect to make cleanup. The invoking chain is :
brcmf_usb_disconnect ->brcmf_usb_disconnect_cb ->brcmf_detach ->brcmf_cfg80211_detach ->kfree(cfg);
While the timeout woker may still be running. This will cause a use-after-free bug on cfg in brcmf_cfg80211_escan_timeout_worker.
Fix it by deleting the timer and canceling the worker in brcmf_cfg80211_detach.

This means the underlying doubly-linked list is temporarily inconsistent, page->prev->next or page->next->prev might not be equal back to page for some page in the ring buffer.
The resize operation in ring_buffer_resize() can be invoked in parallel. It calls rb_check_pages() which can detect the described inconsistency and stop further tracing:

Note that ring_buffer_resize() calls rb_check_pages() only if the parent trace_buffer has recording disabled. Recent commit d78ab792705c ("tracing: Stop current tracer when resizing buffer") causes that it is now always the case which makes it more likely to experience this issue.
The window to hit this race is nonetheless very small. To help reproducing it, one can add a delay loop in rb_get_reader_page():
ret = rb_head_page_replace(reader, cpu_buffer->reader_page); if (!ret) goto spin; for (unsigned i = 0; i < 1U << 26; i++) /* inserted delay loop */ asm volatile ("" : : : "memory"); rb_list_head(reader->list.next)->prev = &cpu_buffer->reader_page->list;

In the Linux kernel, the following vulnerability has been resolved:
serial: max3100: Lock port->lock when calling uart_handle_cts_change()
uart_handle_cts_change() has to be called with port lock taken, Since we run it in a separate work, the lock may not be taken at the time of running. Make sure that it's taken by explicitly doing that. Without it we got a splat:
WARNING: CPU: 0 PID: 10 at drivers/tty/serial/serial_core.c:3491 uart_handle_cts_change+0xa6/0xb0 ... Workqueue: max3100-0 max3100_work [max3100] RIP: 0010:uart_handle_cts_change+0xa6/0xb0 ... max3100_handlerx+0xc5/0x110 [max3100] max3100_work+0x12a/0x340 max3100
In the Linux kernel, the following vulnerability has been resolved:
bpf: Allow delete from sockmap/sockhash only if update is allowed
We have seen an influx of syzkaller reports where a BPF program attached to a tracepoint triggers a locking rule violation by performing a map_delete on a sockmap/sockhash.
We don't intend to support this artificial use scenario. Extend the existing verifier allowed-program-type check for updating sockmap/sockhash to also cover deleting from a map.
From now on only BPF programs which were previously allowed to update sockmap/sockhash can delete from these map types.(CVE-2024-38662)

This results in a iscsi_task use after free, because the common\ncleanup code will do a put on the iscsi_task.\r\n\r\nThis reverts the goto and moves the iscsi_get_conn() to after we\u0026apos;ve checked\nif the iscsi_task is valid.(CVE-2021-47427)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nspi: Fix deadlock when adding SPI controllers on SPI buses\r\n\r\nCurrently we have a global spi_add_lock which we take when adding new\ndevices so that we can check that we\u0026apos;re not trying to reuse a chip\nselect that\u0026apos;s already controlled. This means that if the SPI device is\nitself a SPI controller and triggers the instantiation of further SPI\ndevices we trigger a deadlock as we try to register and instantiate\nthose devices while in the process of doing so for the parent controller\nand hence already holding the global spi_add_lock. Since we only care\nabout concurrency within a single SPI bus move the lock to be per\ncontroller, avoiding the deadlock.\r\n\r\nThis can be easily triggered in the case of spi-mux.(CVE-2021-47469)\r\n\r\n(CVE-2023-39180)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\npowerpc/powernv: Add a null pointer check in opal_powercap_init()\r\n\r\nkasprintf() returns a pointer to dynamically allocated memory\nwhich can be NULL upon failure.(CVE-2023-52696)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\ni2c: core: Run atomic i2c xfer when !preemptible\r\n\r\nSince bae1d3a05a8b, i2c transfers are non-atomic if preemption is\ndisabled. However, non-atomic i2c transfers require preemption (e.g. in\nwait_for_completion() while waiting for the DMA).\r\n\r\npanic() calls preempt_disable_notrace() before calling\nemergency_restart().

Quoting Eric:\n Calling ip_defrag() in output path is also implying skb_orphan(),\n which is buggy because output path relies on sk not disappearing.\r\n\r\n A relevant old patch about the issue was :\n 8282f27449bf (\u0026quot;inet: frag: Always orphan skbs inside ip_defrag()\u0026quot;)\r\n\r\n [..]\r\n\r\n net/ipv4/ip_output.c depends on skb-\u0026gt;sk being set, and probably to an\n inet socket, not an arbitrary one.\r\n\r\n If we orphan the packet in ipvlan, then downstream things like FQ\n packet scheduler will not work properly.\r\n\r\n We need to change ip_defrag() to only use skb_orphan() when really\n needed, ie whenever frag_list is going to be used.\r\n\r\nEric suggested to stash sk in fragment queue and made an initial patch.\nHowever there is a problem with this:\r\n\r\nIf skb is refragmented again right after, ip_do_fragment() will copy\nhead-\u0026gt;sk to the new fragments, and sets up destructor to sock_wfree.\nIOW, we have no choice but to fix up sk_wmem accouting to reflect the\nfully reassembled skb, else wmem will underflow.\r\n\r\nThis change moves the orphan down into the core, to last possible moment.\nAs ip_defrag_offset is aliased with sk_buff-\u0026gt;sk member, we must move the\noffset into the FRAG_CB, else skb-\u0026gt;sk gets clobbered.\r\n\r\nThis allows to delay the orphaning long enough to learn if the skb has\nto be queued or if the skb is completing the reasm queue.\r\n\r\nIn the former case, things work as before, skb is orphaned. This is\nsafe because skb gets queued/stolen and won\u0026apos;t continue past reasm engine.\r\n\r\nIn the latter case, we will steal the skb-\u0026gt;sk reference, reattach it to\nthe head skb, and fix up wmem accouting when inet_frag inflates truesize.(CVE-2024-26921)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nscsi: core: Fix unremoved procfs host directory regression\r\n\r\nCommit fc663711b944 (\u0026quot;scsi: core: Remove the /proc/scsi/${proc_name}\ndirectory earlier\u0026quot;) fixed a bug related to modules loading/unloading, by\nadding a call to scsi_proc_hostdir_rm() on scsi_remove_host(). But that led\nto a potential duplicate call to the hostdir_rm() routine, since it\u0026apos;s also\ncalled from scsi_host_dev_release(). That triggered a regression report,\nwhich was then fixed by commit be03df3d4bfe (\u0026quot;scsi: core: Fix a procfs host\ndirectory removal regression\u0026quot;). The fix just dropped the hostdir_rm() call\nfrom dev_release().\r\n\r\nBut it happens that this proc directory is created on scsi_host_alloc(),\nand that function \u0026quot;pairs\u0026quot; with scsi_host_dev_release(), while\nscsi_remove_host() pairs with scsi_add_host(). In other words, it seems the\nreason for removing the proc directory on dev_release() was meant to cover\ncases in which a SCSI host structure was allocated, but the call to\nscsi_add_host() didn\u0026apos;t happen. And that pattern happens to exist in some\nerror paths, for example.\r\n\r\nSyzkaller causes that by using USB raw gadget device, error\u0026apos;ing on\nusb-storage driver, at usb_stor_probe2(). By checking that path, we can see\nthat the BadDevice label leads to a scsi_host_put() after a SCSI host\nallocation, but there\u0026apos;s no call to scsi_add_host() in such path.

Instead, the change is\ndeferred until the next instance of the interrupt being triggered on the\noriginal CPU.\r\n\r\nWhen the interrupt next triggers on the original CPU, the new affinity is\nenforced within __irq_move_irq().
