CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_conntrack: use get_unaligned_be32() in tcp_sack()
The timestamp-only fast path dereferences the option stream as
*(__be32 *)ptr, which assumes 4-byte alignment that the TCP option
stream does not guarantee. Use get_unaligned_be32() instead, which
reads the value safely and already returns host byte order, so the
htonl() on the comparison constant can be dropped.
This matches the existing get_unaligned_be32() use later in the same
function. |
| In the Linux kernel, the following vulnerability has been resolved:
nvme: validate FDP configuration descriptor sizes
Validate descriptor sizes while walking the FDP configurations log so
dsze == 0 or a descriptor past the log end cannot cause unbounded
iteration or reads past the buffer. |
| In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: validate index entry key bounds
[BUG]
A malformed NTFS directory index entry can advertise a key_size larger
than the bytes actually present in its NTFS_DE payload. Directory lookup
then passes that malformed key to cmp_fnames(), which can read past the
end of the kmalloc'ed index buffer.

[CAUSE]
The index-header validators only validated INDEX_HDR-level geometry.
They did not walk each NTFS_DE to verify entry alignment, subnode
layout, or that key_size fit inside the entry payload. They also
allowed a last sentinel entry to carry a non-zero key_size.
[FIX]
Walk every NTFS_DE in ntfs3's index-header validators and reject
entries with invalid layout, mismatched subnode state, oversized
key_size, or non-zero sentinel keys before lookup or log replay can
consume them. |

wifi: iwlwifi: mvm: validate TX_CMD response layout
TX_CMD parsing uses frame_count to walk status entries and then
read the trailing SCD SSN. Make the minimum-length check follow
that exact runtime layout calculation before parsing the payload.

warn/return in the aggregation handler to document that aggregated
accounting is expected via BA notifications. |

The itemsize matches the namelen, but the namelen is 4096, way larger
than normal name length limit (BTRFS_NAME_LEN, 255).
Meanwhile the memory of the @name is only 255 byte sized, this will cause
out-of-boundary access, and cause the above crash.
[FIX]
Add extra namelen verification for INODE_REF, just like what we have
done in ROOT_REF checks.
Now the crafted image can be rejected gracefully:
BTRFS critical (device dm-2): corrupt leaf: root=5 block=30572544 slot=14 ino=259, invalid inode ref name length, has 4096 expect [1, 255]
BTRFS error (device dm-2): read time tree block corruption detected on logical 30572544 mirror 2

| In the Linux kernel, the following vulnerability has been resolved:
f2fs: validate inline dentry name lengths before conversion
Inline dentry conversion copies names out of the inline dentry area
before checking that each recorded name length fits in the available
filename slots.
A corrupted image can therefore make the conversion path read past
the inline filename storage while building the regular dentry block.
Validate each inline dentry name length against the inline filename
area before copying it. |
| In the Linux kernel, the following vulnerability has been resolved:
virtio-fs: avoid double-free on failed queue setup
virtio_fs_setup_vqs() allocates fs->vqs and fs->mq_map before calling
virtio_find_vqs(). If virtio_find_vqs() fails, the error path frees both
pointers and returns an error to virtio_fs_probe().
virtio_fs_probe() then drops the last kobject reference, and
virtio_fs_ktype_release() frees fs->vqs and fs->mq_map again. This leaves
dangling pointers in struct virtio_fs and can trigger a double-free during
probe failure cleanup.
Set fs->vqs and fs->mq_map to NULL immediately after kfree() in the
virtio_fs_setup_vqs() error path so that the later kobject release sees an
uninitialized state and kfree(NULL) becomes harmless.
This can be reproduced when a broken virtio-fs device advertises more
request queues than the transport actually provides. In that case
virtio_find_vqs() fails while setting up the extra queue, and the probe
path reaches the double-free cleanup sequence. |

virt: acrn: Fix irqfd use-after-free during eventfd shutdown
acrn_irqfd_deassign() and the eventfd EPOLLHUP wakeup can race and free
the same struct hsm_irqfd:
CPU0 CPU1
---- ----
eventfd_release()
wake_up_poll(EPOLLHUP)
hsm_irqfd_wakeup()
queue_work(&irqfd->shutdown)
acrn_irqfd_deassign()
hsm_irqfd_shutdown()
list_del_init()
eventfd_ctx_remove_wait_queue()
eventfd_ctx_put()
kfree(irqfd)
hsm_irqfd_shutdown_work()
container_of(work, ..., shutdown)
irqfd->vm <-- use-after-free
The deassign path freed the irqfd while a shutdown work item was
already queued by EPOLLHUP (or vice versa), so the work item could
resurrect a dangling pointer through container_of().
Switch to the lifetime model used by KVM irqfds:
- Deassign/deinit only deactivate the irqfd: remove it from vm->irqfds
under irqfds_lock and queue the cleanup work.
- hsm_irqfd_shutdown_work() becomes the sole owner that unhooks the
eventfd waitqueue entry, drops the eventfd reference and frees the
irqfd.
- A new HSM_IRQFD_FLAG_SHUTDOWN bit guarded by test_and_set_bit()
ensures the cleanup work is queued at most once, no matter how many
of {EPOLLHUP, deassign, deinit} fire concurrently. This is safe to
call from the waitqueue callback, which runs with wqh->lock held and
IRQs disabled and therefore cannot take irqfds_lock.
- acrn_irqfd_deassign() flushes vm->irqfd_wq before returning so the
eventfd is fully detached on return. acrn_irqfd_deinit() deactivates
every irqfd, flushes the workqueue and only then destroys it, so no
path can queue_work() onto a torn-down workqueue.
- acrn_irqfd_assign() now installs the eventfd waitqueue entry and
publishes the irqfd to vm->irqfds under irqfds_lock, so the irqfd is
never visible to deassign/deinit before its waitqueue entry is in
place, and any EPOLLHUP that fires in the assign window queues
cleanup work that blocks on irqfds_lock until publication is done. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Check bounds for allocate_sdma_queue restore_sdma_id
allocate_sdma_queue has an option where the sdma queue id can be
specified (used by CRIU). We weren't bounds-checking that
value.
Confirm it's less than the maximum number of queues. |
