This matches established kernel.org scoring for USB gadget bind/unbind use-after-frees (e.g. CVE-2025-38555, CVE-2026-63894).\nAC:L - The attacker controls both sides of the race \u2014 the moment of the free (unbind plus closing the last `/dev/snd/control*` descriptor, which is what actually triggers `snd_card_do_free()` and releases the kcontrols) and the moment of the use (UAC volume/mute `SET_CUR` transfers, altsetting changes, or bus suspend) \u2014 so it can be retried and won reliably.\nPR:L - An unprivileged local user can hold and release the ALSA control descriptor to pin the exact instant the kcontrols are freed and can drive the USB-side control transfers via the loopback host stack, consistent with the PR:L assigned to other gadget teardown use-after-frees reached through the same configfs path.\nUI:N - The attacker performs every step itself \u2014 unbind, fd close, and the UAC control traffic \u2014 with no action required from any other user.\nS:U - The use-after-free corrupts kernel heap memory within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The stale `snd_kcontrol` is read after free and its `id` field (including the 64-byte name) is copied into a `snd_ctl_event` delivered to userspace readers of the control device, leaking groomable freed slab contents; a controlled use-after-free read of this kind is a general kernel memory disclosure primitive.\nI:H - `set_active()` and `u_audio_set_volume/mute()` acquire `prm-\u003elock` and write `prm-\u003eactive`/`volume`/`mute` into the already-`kfree()`d `snd_uac_chip`, and `snd_ctl_notify()` performs list insertion on the freed `snd_card`, giving write-after-free and list-corruption primitives that can be leveraged for control-flow hijacking.\nA:H - Use of freed kcontrol, `snd_card`, and `snd_uac_chip` objects \u2014 including spinlock operations and list walks on freed memory \u2014 reliably produces KASAN splats, list corruption, and kernel panics."

Summary

kernel security update

Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

media: lgdt3306a: Add a check against null-pointer-def

The driver should check whether the client provides the platform_data.

The following log reveals it:

In the Linux kernel, the following vulnerability has been resolved:

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:

tls: fix missing memory barrier in tls_init

In tls_init(), a write memory barrier is missing, and store-store reordering may cause NULL dereference in tls_{setsockopt,getsockopt}.

CPU0 CPU1 ----- ----- // In tls_init() // In tls_ctx_create() ctx = kzalloc() ctx->sk_proto = READ_ONCE(sk->sk_prot) -(1)

// In update_sk_prot() WRITE_ONCE(sk->sk_prot, tls_prots) -(2)

                               // In sock_common_setsockopt()
                               READ_ONCE(sk-&gt;sk_prot)-&gt;setsockopt()

                               // In tls_{setsockopt,getsockopt}()
                               ctx-&gt;sk_proto-&gt;setsockopt()    -(3)

In the above scenario, when (1) and (2) are reordered, (3) can observe the NULL value of ctx->sk_proto, causing NULL dereference.

To fix it, we rely on rcu_assign_pointer() which implies the release barrier semantic. By moving rcu_assign_pointer() after ctx->sk_proto is initialized, we can ensure that ctx->sk_proto are visible when changing sk->sk_prot.(CVE-2024-36489)

In the Linux kernel, the following vulnerability has been resolved:

amd/amdkfd: sync all devices to wait all processes being evicted

If there are more than one device doing reset in parallel, the first device will call kfd_suspend_all_processes() to evict all processes on all devices, this call takes time to finish. other device will start reset and recover without waiting. if the process has not been evicted before doing recover, it will be restored, then caused page fault.(CVE-2024-36949)

In the Linux kernel, the following vulnerability has been resolved:

scsi: lpfc: Move NPIV's transport unregistration to after resource clean up

There are cases after NPIV deletion where the fabric switch still believes the NPIV is logged into the fabric. This occurs when a vport is unregistered before the Remove All DA_ID CT and LOGO ELS are sent to the fabric.

Currently fc_remove_host(), which calls dev_loss_tmo for all D_IDs including the fabric D_ID, removes the last ndlp reference and frees the ndlp rport object. This sometimes causes the race condition where the final DA_ID and LOGO are skipped from being sent to the fabric switch.

Fix by moving the fc_remove_host() and scsi_remove_host() calls after DA_ID and LOGO are sent.(CVE-2024-36952)

In the Linux kernel, the following vulnerability has been resolved:

net: ks8851: Queue RX packets in IRQ handler instead of disabling BHs

Currently the driver uses local_bh_disable()/local_bh_enable() in its IRQ handler to avoid triggering net_rx_action() softirq on exit from netif_rx(). The net_rx_action() could trigger this driver .start_xmit callback, which is protected by the same lock as the IRQ handler, so calling the .start_xmit from netif_rx() from the IRQ handler critical section protected by the lock could lead to an attempt to claim the already claimed lock, and a hang.

The local_bh_disable()/local_bh_enable() approach works only in case the IRQ handler is protected by a spinlock, but does not work if the IRQ handler is protected by mutex, i.e. this works for KS8851 with Parallel bus interface, but not for KS8851 with SPI bus interface.

Remove the BH manipulation and instead of calling netif_rx() inside the IRQ handler code protected by the lock, queue all the received SKBs in the IRQ handler into a queue first, and once the IRQ handler exits the critical section protected by the lock, dequeue all the queued SKBs and push them all into netif_rx(). At this point, it is safe to trigger the net_rx_action() softirq, since the netif_rx() call is outside of the lock that protects the IRQ handler.(CVE-2024-36962)

In the Linux kernel, the following vulnerability has been resolved:

remoteproc: mediatek: Make sure IPI buffer fits in L2TCM

The IPI buffer location is read from the firmware that we load to the System Companion Processor, and it's not granted that both the SRAM (L2TCM) size that is defined in the devicetree node is large enough for that, and while this is especially true for multi-core SCP, it's still useful to check on single-core variants as well.

Failing to perform this check may make this driver perform R/W operations out of the L2TCM boundary, resulting (at best) in a kernel panic.

To fix that, check that the IPI buffer fits, otherwise return a failure and refuse to boot the relevant SCP core (or the SCP at all, if this is single core).(CVE-2024-36965)

It seems syzkaller started fuzzing module parameters and triggered shift-out-of-bounds [0] by setting 100 to dctcp_shift_g:

wifi: nl80211: Avoid address calculations via out of bounds array indexing

Before request->channels[] can be used, request->n_channels must be set. Additionally, address calculations for memory after the "channels" array need to be calculated from the allocation base ("request") rather than via the first "out of bounds" index of "channels", otherwise run-time bounds checking will throw a warning.(CVE-2024-38562)

In the Linux kernel, the following vulnerability has been resolved:

bpf: Add BPF_PROG_TYPE_CGROUP_SKB attach type enforcement in BPF_LINK_CREATE

bpf_prog_attach uses attach_type_to_prog_type to enforce proper attach type for BPF_PROG_TYPE_CGROUP_SKB. link_create uses bpf_prog_get and relies on bpf_prog_attach_check_attach_type to properly verify prog_type <> attach_type association.

Add missing attach_type enforcement for the link_create case. Otherwise, it's currently possible to attach cgroup_skb prog types to other cgroup hooks.(CVE-2024-38564)

rcu-tasks: Fix show_rcu_tasks_trace_gp_kthread buffer overflow

There is a possibility of buffer overflow in show_rcu_tasks_trace_gp_kthread() if counters, passed to sprintf() are huge. Counter numbers, needed for this are unrealistically high, but buffer overflow is still possible.

nilfs2: fix potential hang in nilfs_detach_log_writer()

Syzbot has reported a potential hang in nilfs_detach_log_writer() called during nilfs2 unmount.

Analysis revealed that this is because nilfs_segctor_sync(), which synchronizes with the log writer thread, can be called after nilfs_segctor_destroy() terminates that thread, as shown in the call trace below:

nilfs_detach_log_writer nilfs_segctor_destroy nilfs_segctor_kill_thread --> Shut down log writer thread flush_work nilfs_iput_work_func nilfs_dispose_list iput nilfs_evict_inode nilfs_transaction_commit nilfs_construct_segment (if inode needs sync) nilfs_segctor_sync --> Attempt to synchronize with log writer thread *** DEADLOCK ***

Fix this issue by changing nilfs_segctor_sync() so that the log writer thread returns normally without synchronizing after it terminates, and by forcing tasks that are already waiting to complete once after the thread terminates.

The skipped inode metadata flushout will then be processed together in the subsequent cleanup work in nilfs_segctor_destroy().(CVE-2024-38582)

The root cause is that, in lookup_rec(), ftrace record of some address is being searched in ftrace pages of some module, but those ftrace pages at the same time is being freed in ftrace_release_mod() as the corresponding module is being deleted:

       CPU1                       |      CPU2

register_kprobes() { | delete_module() { check_kprobe_address_safe() { | arch_check_ftrace_location() { | ftrace_location() { | lookup_rec() // USE! | ftrace_release_mod() // Free!

To fix this issue: 1. Hold rcu lock as accessing ftrace pages in ftrace_location_range(); 2. Use ftrace_location_range() instead of lookup_rec() in ftrace_location(); 3. Call synchronize_rcu() before freeing any ftrace pages both in ftrace_process_locs()/ftrace_release_mod()/ftrace_free_mem().(CVE-2024-38588)

Root cause is that commit 301867b1c168 ("md/raid10: check slab-out-of-bounds in md_bitmap_get_counter") return early from md_bitmap_get_counter(), without setting returned blocks.

Fix this problem by always set returned blocks from md_bitmap_get_counter"(), as it used to be.

jffs2: prevent xattr node from overflowing the eraseblock

Add a check to make sure that the requested xattr node size is no larger than the eraseblock minus the cleanmarker.

Unlike the usual inode nodes, the xattr nodes aren't split into parts and spread across multiple eraseblocks, which means that a xattr node must not occupy more than one eraseblock. If the requested xattr value is too large, the xattr node can spill onto the next eraseblock, overwriting the nodes and causing errors such as:

jffs2: argh. node added in wrong place at 0x0000b050(2) jffs2: nextblock 0x0000a000, expected at 0000b00c jffs2: error: (823) do_verify_xattr_datum: node CRC failed at 0x01e050, read=0xfc892c93, calc=0x000000 jffs2: notice: (823) jffs2_get_inode_nodes: Node header CRC failed at 0x01e00c. {848f,2fc4,0fef511f,59a3d171} jffs2: Node at 0x0000000c with length 0x00001044 would run over the end of the erase block jffs2: Perhaps the file system was created with the wrong erase size? jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000010: 0x1044 instead

ax25: Fix reference count leak issues of ax25_dev

The ax25_addr_ax25dev() and ax25_dev_device_down() exist a reference count leak issue of the object "ax25_dev".

Memory leak issue in ax25_addr_ax25dev():

The reference count of the object "ax25_dev" can be increased multiple times in ax25_addr_ax25dev(). This will cause a memory leak.

Memory leak issues in ax25_dev_device_down():

The reference count of ax25_dev is set to 1 in ax25_dev_device_up() and then increase the reference count when ax25_dev is added to ax25_dev_list. As a result, the reference count of ax25_dev is 2. But when the device is shutting down. The ax25_dev_device_down() drops the reference count once or twice depending on if we goto unlock_put or not, which will cause memory leak.

As for the issue of ax25_addr_ax25dev(), it is impossible for one pointer to be on a list twice. So add a break in ax25_addr_ax25dev(). As for the issue of ax25_dev_device_down(), increase the reference count of ax25_dev once in ax25_dev_device_up() and decrease the reference count of ax25_dev after it is removed from the ax25_dev_list.(CVE-2024-38602)

drivers/virt/acrn: fix PFNMAP PTE checks in acrn_vm_ram_map()

Patch series "mm: follow_pte() improvements and acrn follow_pte() fixes".

Patch #1 fixes a bunch of issues I spotted in the acrn driver. It compiles, that's all I know. I'll appreciate some review and testing from acrn folks.

Patch #2+#3 improve follow_pte(), passing a VMA instead of the MM, adding more sanity checks, and improving the documentation. Gave it a quick test on x86-64 using VM_PAT that ends up using follow_pte().

This patch (of 3):

We currently miss handling various cases, resulting in a dangerous follow_pte() (previously follow_pfn()) usage.

(1) We're not checking PTE write permissions.

Maybe we should simply always require pte_write() like we do for pin_user_pages_fast(FOLL_WRITE)? Hard to tell, so let's check for ACRN_MEM_ACCESS_WRITE for now.

(2) We're not rejecting refcounted pages.

As we are not using MMU notifiers, messing with refcounted pages is dangerous and can result in use-after-free. Let's make sure to reject them.

(3) We are only looking at the first PTE of a bigger range.

We only lookup a single PTE, but memmap->len may span a larger area. Let's loop over all involved PTEs and make sure the PFN range is actually contiguous. Reject everything else: it couldn't have worked either way, and rather made use access PFNs we shouldn't be accessing.(CVE-2024-38610)

file_ida is allocated during cdev open and is freed accordingly during cdev release. This sequence is guaranteed by driver file operations. Therefore, there is no need to destroy an already empty file_ida when the WQ cdev is removed.

Worse, ida_free() in cdev release may happen after destruction of file_ida per WQ cdev. This can lead to accessing an id in file_ida after it has been destroyed, resulting in a kernel panic.

Remove ida_destroy(&file_ida) to address these issues.(CVE-2024-38629)

bonding: fix oops during rmmod

"rmmod bonding" causes an oops ever since commit cc317ea3d927 ("bonding: remove redundant NULL check in debugfs function"). Here are the relevant functions being called:

bonding_exit() bond_destroy_debugfs() debugfs_remove_recursive(bonding_debug_root); bonding_debug_root = NULL; <--------- SET TO NULL HERE bond_netlink_fini() rtnl_link_unregister() __rtnl_link_unregister() unregister_netdevice_many_notify() bond_uninit() bond_debug_unregister() (commit removed check for bonding_debug_root == NULL) debugfs_remove() simple_recursive_removal() down_write() -> OOPS

However, reverting the bad commit does not solve the problem completely because the original code contains a race that could cause the same oops, although it was much less likely to be triggered unintentionally:

CPU1 rmmod bonding bonding_exit() bond_destroy_debugfs() debugfs_remove_recursive(bonding_debug_root);

CPU2 echo -bond0 > /sys/class/net/bonding_masters bond_uninit() bond_debug_unregister() if (!bonding_debug_root)

CPU1 bonding_debug_root = NULL;

So do NOT revert the bad commit (since the removed checks were racy anyway), and instead change the order of actions taken during module removal. The same oops can also happen if there is an error during module init, so apply the same fix there.(CVE-2024-39296)

If p9_check_errors() fails early in p9_client_rpc(), req->rc.tag will not be properly initialized. However, trace_9p_client_res() ends up trying to print it out anyway before p9_client_rpc() finishes.

Fix this issue by assigning default values to p9_fcall fields such as 'tag' and (just in case KMSAN unearths something new) 'id' during the tag allocation stage.(CVE-2024-39301)

Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.(CVE-2024-39362)

In the Linux kernel, the following vulnerability has been resolved:

io_uring: check for non-NULL file pointer in io_file_can_poll()

In earlier kernels, it was possible to trigger a NULL pointer dereference off the forced async preparation path, if no file had been assigned. The trace leading to that looks as follows:

because the request is marked forced ASYNC and has a bad file fd, and hence takes the forced async prep path.

Current kernels with the request async prep cleaned up can no longer hit this issue, but for ease of backporting, let's add this safety check in here too as it really doesn't hurt. For both cases, this will inevitably end with a CQE posted with -EBADF.(CVE-2024-39371)

In the Linux kernel, the following vulnerability has been resolved:

clk: bcm: rpi: Assign ->num before accessing ->hws

Commit f316cdff8d67 ("clk: Annotate struct clk_hw_onecell_data with __counted_by") annotated the hws member of 'struct clk_hw_onecell_data' with __counted_by, which informs the bounds sanitizer about the number of elements in hws, so that it can warn when hws is accessed out of bounds. As noted in that change, the __counted_by member must be initialized with the number of elements before the first array access happens, otherwise there will be a warning from each access prior to the initialization because the number of elements is zero. This occurs in raspberrypi_discover_clocks() due to ->num being assigned after ->hws has been accessed:

UBSAN: array-index-out-of-bounds in drivers/clk/bcm/clk-raspberrypi.c:374:4 index 3 is out of range for type 'struct clk_hw [] __counted_by(num)' (aka 'struct clk_hw []')

Move the ->num initialization to before the first access of ->hws, which clears up the warning.(CVE-2024-39461)

In the Linux kernel, the following vulnerability has been resolved:

thermal/drivers/qcom/lmh: Check for SCM availability at probe

Up until now, the necessary scm availability check has not been performed, leading to possible null pointer dereferences (which did happen for me on RB1).

Fix that.(CVE-2024-39466)

The root cause is we missed to do sanity check on i_xattr_nid during f2fs_iget(), so that in fiemap() path, current_nat_addr() will access nat_bitmap w/ offset from invalid i_xattr_nid, result in triggering kasan bug report, fix it.(CVE-2024-39467)

In the Linux kernel, the following vulnerability has been resolved:

smb: client: fix deadlock in smb2_find_smb_tcon()

In the Linux kernel, the following vulnerability has been resolved:

eventfs: Fix a possible null pointer dereference in eventfs_find_events()

In function eventfs_find_events,there is a potential null pointer that may be caused by calling update_events_attr which will perform some operations on the members of the ei struct when ei is NULL.

Hence,When ei->is_freed is set,return NULL directly.(CVE-2024-39470)

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(). A vector is allocated from the new CPU,\nbut the old vector on the original CPU remains and is not immediately\nreclaimed. Instead, apicd-\u0026gt;move_in_progress is flagged, and the reclaiming\nprocess is delayed until the next trigger of the interrupt on the new CPU.\r\n\r\nUpon the subsequent triggering of the interrupt on the new CPU,\nirq_complete_move() adds a task to the old CPU\u0026apos;s vector_cleanup list if it\nremains online. Subsequently, the timer on the old CPU iterates over its\nvector_cleanup list, reclaiming old vectors.\r\n\r\nHowever, a rare scenario arises if the old CPU is outgoing before the\ninterrupt triggers again on the new CPU.\r\n\r\nIn that case irq_force_complete_move() is not invoked on the outgoing CPU\nto reclaim the old apicd-\u0026gt;prev_vector because the interrupt isn\u0026apos;t currently\naffine to the outgoing CPU, and irq_needs_fixup() returns false. Even\nthough __vector_schedule_cleanup() is later called on the new CPU, it\ndoesn\u0026apos;t reclaim apicd-\u0026gt;prev_vector; instead, it simply resets both\napicd-\u0026gt;move_in_progress and apicd-\u0026gt;prev_vector to 0.\r\n\r\nAs a result, the vector remains unreclaimed in vector_matrix, leading to a\nCPU vector leak.\r\n\r\nTo address this issue, move the invocation of irq_force_complete_move()\nbefore the irq_needs_fixup() call to reclaim apicd-\u0026gt;prev_vector, if the\ninterrupt is currently or used to be affine to the outgoing CPU.\r\n\r\nAdditionally, reclaim the vector in __vector_schedule_cleanup() as well,\nfollowing a warning message, although theoretically it should never see\napicd-\u0026gt;move_in_progress with apicd-\u0026gt;prev_cpu pointing to an offline CPU.(CVE-2024-31076)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\ntls: fix missing memory barrier in tls_init\r\n\r\nIn tls_init(), a write memory barrier is missing, and store-store\nreordering may cause NULL dereference in tls_{setsockopt,getsockopt}.\r\n\r\nCPU0                               CPU1\n-----                              -----\n// In tls_init()\n// In tls_ctx_create()\nctx = kzalloc()\nctx-\u0026gt;sk_proto = READ_ONCE(sk-\u0026gt;sk_prot) -(1)\r\n\r\n// In update_sk_prot()\nWRITE_ONCE(sk-\u0026gt;sk_prot, tls_prots)     -(2)\r\n\r\n                                   // In sock_common_setsockopt()\n                                   READ_ONCE(sk-\u0026gt;sk_prot)-\u0026gt;setsockopt()\r\n\r\n                                   // In tls_{setsockopt,getsockopt}()\n                                   ctx-\u0026gt;sk_proto-\u0026gt;setsockopt()    -(3)\r\n\r\nIn the above scenario, when (1) and (2) are reordered, (3) can observe\nthe NULL value of ctx-\u0026gt;sk_proto, causing NULL dereference.\r\n\r\nTo fix it, we rely on rcu_assign_pointer() which implies the release\nbarrier semantic. By moving rcu_assign_pointer() after ctx-\u0026gt;sk_proto is\ninitialized, we can ensure that ctx-\u0026gt;sk_proto are visible when\nchanging sk-\u0026gt;sk_prot.(CVE-2024-36489)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\namd/amdkfd: sync all devices to wait all processes being evicted\r\n\r\nIf there are more than one device doing reset in parallel, the first\ndevice will call kfd_suspend_all_processes() to evict all processes\non all devices, this call takes time to finish. other device will\nstart reset and recover without waiting. if the process has not been\nevicted before doing recover, it will be restored, then caused page\nfault.(CVE-2024-36949)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nscsi: lpfc: Move NPIV\u0026apos;s transport unregistration to after resource clean up\r\n\r\nThere are cases after NPIV deletion where the fabric switch still believes\nthe NPIV is logged into the fabric.  This occurs when a vport is\nunregistered before the Remove All DA_ID CT and LOGO ELS are sent to the\nfabric.\r\n\r\nCurrently fc_remove_host(), which calls dev_loss_tmo for all D_IDs including\nthe fabric D_ID, removes the last ndlp reference and frees the ndlp rport\nobject.  This sometimes causes the race condition where the final DA_ID and\nLOGO are skipped from being sent to the fabric switch.\r\n\r\nFix by moving the fc_remove_host() and scsi_remove_host() calls after DA_ID\nand LOGO are sent.(CVE-2024-36952)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nnet: ks8851: Queue RX packets in IRQ handler instead of disabling BHs\r\n\r\nCurrently the driver uses local_bh_disable()/local_bh_enable() in its\nIRQ handler to avoid triggering net_rx_action() softirq on exit from\nnetif_rx(). The net_rx_action() could trigger this driver .start_xmit\ncallback, which is protected by the same lock as the IRQ handler, so\ncalling the .start_xmit from netif_rx() from the IRQ handler critical\nsection protected by the lock could lead to an attempt to claim the\nalready claimed lock, and a hang.\r\n\r\nThe local_bh_disable()/local_bh_enable() approach works only in case\nthe IRQ handler is protected by a spinlock, but does not work if the\nIRQ handler is protected by mutex, i.e. this works for KS8851 with\nParallel bus interface, but not for KS8851 with SPI bus interface.\r\n\r\nRemove the BH manipulation and instead of calling netif_rx() inside\nthe IRQ handler code protected by the lock, queue all the received\nSKBs in the IRQ handler into a queue first, and once the IRQ handler\nexits the critical section protected by the lock, dequeue all the\nqueued SKBs and push them all into netif_rx(). At this point, it is\nsafe to trigger the net_rx_action() softirq, since the netif_rx()\ncall is outside of the lock that protects the IRQ handler.(CVE-2024-36962)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nremoteproc: mediatek: Make sure IPI buffer fits in L2TCM\r\n\r\nThe IPI buffer location is read from the firmware that we load to the\nSystem Companion Processor, and it\u0026apos;s not granted that both the SRAM\n(L2TCM) size that is defined in the devicetree node is large enough\nfor that, and while this is especially true for multi-core SCP, it\u0026apos;s\nstill useful to check on single-core variants as well.\r\n\r\nFailing to perform this check may make this driver perform R/W\noperations out of the L2TCM boundary, resulting (at best) in a\nkernel panic.\r\n\r\nTo fix that, check that the IPI buffer fits, otherwise return a\nfailure and refuse to boot the relevant SCP core (or the SCP at\nall, if this is single core).(CVE-2024-36965)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nvirtio: delete vq in vp_find_vqs_msix() when request_irq() fails\r\n\r\nWhen request_irq() fails, error path calls vp_del_vqs(). There, as vq is\npresent in the list, free_irq() is called for the same vector.
