Title
ext4: dax: fix overflowing extents beyond inode size when partially writing
Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: dax: fix overflowing extents beyond inode size when partially writing
The dax_iomap_rw() does two things in each iteration: map written blocks
and copy user data to blocks. If the process is killed by user(See signal
handling in dax_iomap_iter()), the copied data will be returned and added
on inode size, which means that the length of written extents may exceed
the inode size, then fsck will fail. An example is given as:
dd if=/dev/urandom of=file bs=4M count=1
dax_iomap_rw
iomap_iter // round 1
ext4_iomap_begin
ext4_iomap_alloc // allocate 0~2M extents(written flag)
dax_iomap_iter // copy 2M data
iomap_iter // round 2
iomap_iter_advance
iter->pos += iter->processed // iter->pos = 2M
ext4_iomap_begin
ext4_iomap_alloc // allocate 2~4M extents(written flag)
dax_iomap_iter
fatal_signal_pending
done = iter->pos - iocb->ki_pos // done = 2M
ext4_handle_inode_extension
ext4_update_inode_size // inode size = 2M
fsck reports: Inode 13, i_size is 2097152, should be 4194304. Fix?
Fix the problem by truncating extents if the written length is smaller
than expected.

Title
kthread: unpark only parked kthread
Summary
In the Linux kernel, the following vulnerability has been resolved:
kthread: unpark only parked kthread
Calling into kthread unparking unconditionally is mostly harmless when
the kthread is already unparked. The wake up is then simply ignored
because the target is not in TASK_PARKED state.
However if the kthread is per CPU, the wake up is preceded by a call
to kthread_bind() which expects the task to be inactive and in
TASK_PARKED state, which obviously isn't the case if it is unparked.
As a result, calling kthread_stop() on an unparked per-cpu kthread
triggers such a warning:
WARNING: CPU: 0 PID: 11 at kernel/kthread.c:525 __kthread_bind_mask kernel/kthread.c:525

No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The loop dereferences a list element already unlinked inside the body and reads through pointers taken from it (`test_bit(group - 1, nlk-\u003egroups)`), and the missing `ngroups` bound check \u2014 present in the sibling `netlink_update_listeners()` \u2014 makes that an out-of-bounds slab read at an attacker-chosen group index, a stale-object read primitive usable to disclose adjacent kernel heap contents.\nI:H - The same code path writes through the stale/undersized object \u2014 `__assign_bit(group - 1, nlk-\u003egroups, new)` and `nlk-\u003esubscriptions = subscriptions` \u2014 so once the freed or overrun slab region is groomed by the attacker this becomes an arbitrary-bit clear at an attacker-influenced address, plus corruption of the `mc_list` linkage itself, which is sufficient for control-flow hijacking.\nA:H - The committed reproduction is a hard kernel crash \u2014 \"Oops: Kernel access of bad area, sig: 11\" at `netlink_update_socket_mc+0x3c` under `__netlink_clear_multicast_users()` \u2014 and the corruption happens while `nl_table_lock` is held via `netlink_table_grab()` (`write_lock_irq`), so a mangled list also wedges the entire netlink subsystem."

[ 55.020411] note: v3d_bin[166] exited with preempt_count 1
This issue arises because, upon closing the file descriptor (which happens
when we interrupt `kmscube`), the active performance monitor is not
stopped. Although all perfmons are destroyed in `v3d_perfmon_close_file()`,
the active performance monitor's pointer (`v3d->active_perfmon`) is still
retained.
If `kmscube` is run again, the driver will attempt to stop the active
performance monitor using the stale pointer in `v3d->active_perfmon`.
However, this pointer is no longer valid because the previous process has
already terminated, and all performance monitors associated with it have
been destroyed and freed.
To fix this, when the active performance monitor belongs to a given
process, explicitly stop it before destroying and freeing it.

"value": "AV:L - The vulnerability is reached exclusively through ioctls on the local DRM render node /dev/dri/renderD128 (V3D_PERFMON_CREATE plus V3D_SUBMIT_CL/CSD), requiring a local file descriptor on the device. There is no network or remote-peer input path, and the GPU is an integrated SoC block rather than a pluggable device.\nAC:L - This is a deterministic stale-pointer bug, not a race \u2014 the attacker controls both the free (close the fd) and the use (submit the next job), with an unbounded window in between to heap-spray the reclaimed chunk. Upstream reproduces it simply by running kmscube twice, and the attacker can even select the target kmalloc cache by choosing ncounters.\nPR:L - All required ioctls are DRM_RENDER_ALLOW and DRM_AUTH is automatically satisfied for render clients (drm_ioctl.c:550), so no capability, DRM master, or authentication is needed \u2014 only an open fd on the render node, which ordinary logged-in users and GPU-enabled containers routinely have. No root or init-namespace privilege is involved.\nUI:N - The attacker performs every step itself: create perfmon, submit a job, close the fd, spray the heap, then submit another job to trigger the use-after-free. No victim action is required, though the global stale pointer will also fire on any other user\u0027s GPU submission.\nS:U - The corruption is confined to kernel heap memory within the same security authority; no VM, IOMMU, or hypervisor boundary is crossed. It does cross a process boundary (one user\u0027s stale pointer corrupts memory during another user\u0027s job), but that remains a standard kernel privilege-escalation scope.\nC:H - The use-after-free reads freed memory (ncounters, mutex state) that the attacker can populate via heap spray, and the resulting heap corruption is readily leveraged into arbitrary kernel memory disclosure by tampering with length/pointer fields of adjacent reclaimed objects such as msg_msg or pipe_buffer.\nI:H - v3d_perfmon_stop() performs a read-modify-write loop (perfmon-\u003evalues[i] += ...) into the freed/reclaimed object with the iteration count taken from that same attacker-controlled memory, writing u64s up to roughly 2 KB past the allocation into neighbouring slab objects. Combined with mutex_lock() on attacker-controlled memory, this yields a heap-corruption primitive suitable for control-flow hijacking.\nA:H - The upstream bug report is a fatal kernel oops (level-1 translation fault in __mutex_lock) in the v3d_bin scheduler kthread, which exits with preempt_count 1 leaving the mutex held and the GPU scheduler wedged. Any unprivileged user can trigger this crash repeatedly and reliably."

Title
slip: make slhc_remember() more robust against malicious packets
Summary
In the Linux kernel, the following vulnerability has been resolved:
slip: make slhc_remember() more robust against malicious packets
syzbot found that slhc_remember() was missing checks against
malicious packets [1].
slhc_remember() only checked the size of the packet was at least 20,
which is not good enough.
We need to make sure the packet includes the IPv4 and TCP header
that are supposed to be carried.
Add iph and th pointers to make the code more readable.

"value": "AV:N - slhc_remember() is driven directly by received PPP frames via ppp_receive_nonmp_frame(), and ppp_input() is entered from pptp.c (PPP over GRE) and l2tp_ppp.c (PPP over L2TP/UDP), both of which are routable across the Internet, as well as PPPoE on the local segment. A remote PPP peer or an attacker injecting into an established PPTP/L2TP session delivers the malformed VJ-uncompressed frame with no local access.\nAC:L - The attacker fully controls the frame; setting ihl=15 with a 60-byte body makes the ip_fast_csum() gate trivially satisfiable since all checksummed bytes are attacker-supplied, and the OOB read succeeds deterministically regardless of heap contents. No race, no memory-layout precondition, and VJ compression is enabled by default in pppd.\nPR:N - The remote PPP peer needs no privileges or credentials on the target host \u2014 a rogue PPPoE access concentrator or PPTP/L2TP server is the peer by definition, and PPTP-GRE demultiplexing authenticates nothing beyond source address and call ID. Even the local syzbot path only requires ns_capable(CAP_NET_ADMIN), reachable by any unprivileged user via unshare -Urn.\nUI:N - Exploitation happens entirely through frames received on an already-established PPP link, which is normal operational state. No action by any user or administrator is needed at exploit time.\nS:U - The out-of-bounds access and its consequences are confined to the kernel\u0027s own memory and network stack, with no crossing into a different security authority such as a hypervisor or IOMMU boundary.\nC:H - Up to 60 bytes of uninitialized/stale kernel heap are read past the packet into cs_tcp and cs_tcpopt, and a follow-up VJ-compressed frame makes slhc_uncompress() rebuild that data into a well-formed IP packet with an attacker-chosen destination address, exfiltrating kernel memory to the attacker. The primitive is repeatable without limit, giving broad heap disclosure rather than a bounded few-byte leak.\nI:H - Uninitialized memory becomes cs_tcp.doff, which together with cs_ip.ihl drives hdrlen up to 120 in slhc_uncompress(); sl_bump() only reserves 80 bytes before that call, so the resulting memmove/memcpy writes past the kmalloc\u0027d sl-\u003erbuff, giving heap corruption. The corrupted decompression state also causes the kernel to inject attacker-shaped packets carrying heap contents into the local network stack.\nA:H - The out-of-bounds read plus the resulting oversized hdrlen leads to heap overwrite past sl-\u003erbuff on the SLIP path and to malformed reconstructed packets, and on hardened or KASAN/KMSAN-instrumented kernels the access itself triggers an immediate report and panic. The condition is remotely and repeatedly triggerable, so a persistent crash is achievable."

Title
ppp: fix ppp_async_encode() illegal access
Summary
In the Linux kernel, the following vulnerability has been resolved:
ppp: fix ppp_async_encode() illegal access
syzbot reported an issue in ppp_async_encode() [1]
In this case, pppoe_sendmsg() is called with a zero size.
Then ppp_async_encode() is called with an empty skb.

Title
netfilter: xtables: avoid NFPROTO_UNSPEC where needed
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: xtables: avoid NFPROTO_UNSPEC where needed
syzbot managed to call xt_cluster match via ebtables:
WARNING: CPU: 0 PID: 11 at net/netfilter/xt_cluster.c:72 xt_cluster_mt+0x196/0x780
[..]
ebt_do_table+0x174b/0x2a40
Module registers to NFPROTO_UNSPEC, but it assumes ipv4/ipv6 packet
processing. As this is only useful to restrict locally terminating
TCP/UDP traffic, register this for ipv4 and ipv6 family only.
Pablo points out that this is a general issue, direct users of the
set/getsockopt interface can call into targets/matches that were only
intended for use with ip(6)tables.
Check all UNSPEC matches and targets for similar issues:
- matches and targets are fine except if they assume skb_network_header()
is valid -- this is only true when called from inet layer: ip(6) stack
pulls the ip/ipv6 header into linear data area.
- targets that return XT_CONTINUE or other xtables verdicts must be
restricted too, they are incompatbile with the ebtables traverser, e.g.
EBT_CONTINUE is a completely different value than XT_CONTINUE.
Most matches/targets are changed to register for NFPROTO_IPV4/IPV6, as
they are provided for use by ip(6)tables.
The MARK target is also used by arptables, so register for NFPROTO_ARP too.
While at it, bail out if connbytes fails to enable the corresponding
conntrack family.
This change passes the selftests in iptables.git.

Title
net/sched: accept TCA_STAB only for root qdisc
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: accept TCA_STAB only for root qdisc
Most qdiscs maintain their backlog using qdisc_pkt_len(skb)
on the assumption it is invariant between the enqueue()
and dequeue() handlers.
Unfortunately syzbot can crash a host rather easily using
a TBF + SFQ combination, with an STAB on SFQ [1]
We can't support TCA_STAB on arbitrary level, this would
require to maintain per-qdisc storage.

Title
igb: Do not bring the device up after non-fatal error
Summary
In the Linux kernel, the following vulnerability has been resolved:
igb: Do not bring the device up after non-fatal error
Commit 004d25060c78 ("igb: Fix igb_down hung on surprise removal")
changed igb_io_error_detected() to ignore non-fatal pcie errors in order
to avoid hung task that can happen when igb_down() is called multiple
times. This caused an issue when processing transient non-fatal errors.
igb_io_resume(), which is called after igb_io_error_detected(), assumes
that device is brought down by igb_io_error_detected() if the interface
is up. This resulted in panic with stacktrace below.

To fix this issue igb_io_resume() checks if the interface is running and
the device is not down this means igb_io_error_detected() did not bring
the device down and there is no need to bring it up.

Title
i40e: Fix macvlan leak by synchronizing access to mac_filter_hash
Summary
In the Linux kernel, the following vulnerability has been resolved:
i40e: Fix macvlan leak by synchronizing access to mac_filter_hash
This patch addresses a macvlan leak issue in the i40e driver caused by
concurrent access to vsi->mac_filter_hash. The leak occurs when multiple
threads attempt to modify the mac_filter_hash simultaneously, leading to
inconsistent state and potential memory leaks.
To fix this, we now wrap the calls to i40e_del_mac_filter() and zeroing
vf->default_lan_addr.addr with spin_lock/unlock_bh(&vsi->mac_filter_hash_lock),
ensuring atomic operations and preventing concurrent access.
Additionally, we add lockdep_assert_held(&vsi->mac_filter_hash_lock) in
i40e_add_mac_filter() to help catch similar issues in the future.
Reproduction steps:
1. Spawn VFs and configure port vlan on them.
2. Trigger concurrent macvlan operations (e.g., adding and deleting
portvlan and/or mac filters).
3. Observe the potential memory leak and inconsistent state in the
mac_filter_hash.
This synchronization ensures the integrity of the mac_filter_hash and prevents
the described leak.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ni40e: Fix macvlan leak by synchronizing access to mac_filter_hash\n\nThis patch addresses a macvlan leak issue in the i40e driver caused by\nconcurrent access to vsi-\u003emac_filter_hash. The leak occurs when multiple\nthreads attempt to modify the mac_filter_hash simultaneously, leading to\ninconsistent state and potential memory leaks.\n\nTo fix this, we now wrap the calls to i40e_del_mac_filter() and zeroing\nvf-\u003edefault_lan_addr.addr with spin_lock/unlock_bh(\u0026vsi-\u003emac_filter_hash_lock),\nensuring atomic operations and preventing concurrent access.\n\nAdditionally, we add lockdep_assert_held(\u0026vsi-\u003emac_filter_hash_lock) in\ni40e_add_mac_filter() to help catch similar issues in the future.\n\nReproduction steps:\n1. Spawn VFs and configure port vlan on them.\n2. Trigger concurrent macvlan operations (e.g., adding and deleting\n\tportvlan and/or mac filters).\n3. Observe the potential memory leak and inconsistent state in the\n\tmac_filter_hash.\n\nThis synchronization ensures the integrity of the mac_filter_hash and prevents\nthe described leak."

This is logical local access to the device, so Local.\nAC:L - The attacker deterministically controls the unlocked side \u2014 `vf-\u003edriver_caps` is taken verbatim from the VF message so the gating condition is attacker-selected, and `VIRTCHNL_OP_GET_VF_RESOURCES` can be replayed without limit \u2014 while pre-populating MAC/VLAN filters lengthens the unlocked hash walk, which runs in preemptible workqueue context; on lockdep kernels the assertion fires with no race needed at all.\nPR:L - The attacker is the owner of an assigned VF \u2014 a guest VM tenant or a VFIO/DPDK userspace driver \u2014 holding no privilege on the host kernel beyond the granted device, and no host-side capability, root, or trusted-VF flag is required (the path runs before any privilege check and untrusted VFs reach it).\nUI:N - The guest drives the vulnerable path entirely on its own by writing virtchnl messages to its mailbox; no victim action is needed to enable the attack, and the deterministic lockdep-assert path requires nothing from anyone else.\nS:C - The virtchnl handler is the PF\u0027s service surface for a VF that belongs to a separate security authority (guest VM / VFIO container), and successful exploitation corrupts host kernel memory \u2014 a guest-to-host boundary crossing analogous to a hypervisor escape.\nC:H - Unsynchronized `hash_for_each_safe()` racing a concurrent `kfree()` in `i40e_sync_vsi_filters()` produces a use-after-free on a kmalloc-32 `struct i40e_mac_filter`, and corrupted hlist traversal follows attacker-groomable pointers into reallocated memory, enabling kernel heap disclosure.\nI:H - `__i40e_del_filter()` writes `f-\u003estate` into freed memory and `hash_del()` performs `*pprev = next` using pointers from a reallocated, attacker-sprayed 32-byte object \u2014 a write-what-where primitive; concurrent unlink from both sides also yields a double free.\nA:H - Concurrent unlocked hlist manipulation corrupts the filter hash, causing use-after-free, double free, and lost entries (the reported leak), any of which panic the host kernel; on `CONFIG_PROVE_LOCKING` builds a guest can also trigger the `lockdep_assert_held()` WARN on demand, which is fatal under `panic_on_warn`."
