In the Linux kernel, the following vulnerability has been resolved:
bpf: Add missing access_ok call to copy_user_syms
As reported by sashiko we use __get_user without prior access_ok call on the

Plus removing the err check in the error path, because it's not needed and
also we can return -ENOMEM directly from the first kvmalloc_array fail path.

🚨 CVE-2026-80866
In the Linux kernel, the following vulnerability has been resolved:
tipc: avoid busy looping in tipc_exit_net()
Blamed commit introduced a busy-wait loop in tipc_exit_net()
to wait for pending UDP bearer cleanup works to complete:
while (atomic_read(&tn->wq_count))
cond_resched();
This loop can busy-wait for a long time if cond_resched() is a NOP. This
typically happens if the netns exit is executed by a high priority task,
or under kernels configured without preemption (CONFIG_PREEMPT_NONE). In
such cases, it wastes CPU cycles and can lead to soft lockups.
Fix this by replacing the busy loop with wait_var_event(), allowing the
thread to sleep properly until the work queue count reaches zero.
Accordingly, update cleanup_bearer() to use atomic_dec_and_test() and
wake_up_var() to wake up the waiter when the count drops to zero.
This uses the global wait queue hash table, avoiding the need to bloat
struct tipc_net with a wait_queue_head_t. The atomic_dec_and_test()
provides the necessary memory barrier to ensure the wakeup is not missed.

🚨 CVE-2026-80869
In the Linux kernel, the following vulnerability has been resolved:
ntfs: bound the attribute-list entry in ntfs_read_inode_mount()
The $MFT attribute-list walk in ntfs_read_inode_mount() validates each
entry only with "(u8 *)al_entry + 6 > al_end" and
"(u8 *)al_entry + le16_to_cpu(al_entry->length) > al_end", but then reads
al_entry->lowest_vcn (an __le64 at offset 8) and al_entry->mft_reference
(offset 16) -- fields beyond the 6 bytes proven in range. al_entry->length
is attacker-controlled and only required non-zero, so a short entry (e.g.
length 8) placed at the tail passes both checks while the lowest_vcn /
mft_reference reads fall past al_end.
al_end is ni->attr_list + attr_list_size (the on-disk size); the buffer is
kvzalloc(round_up(attr_list_size, SECTOR_SIZE)), so the sector rounding
usually absorbs the over-read -- but when attr_list_size is a multiple of
SECTOR_SIZE there is no slack and a crafted $MFT attribute list produces an
out-of-bounds read at mount time.
Validate the entry with ntfs_attr_list_entry_is_valid() (added in patch
1/3) before dereferencing it, matching the bound the other attribute-list
walks now use. The validator already requires the length to cover the fixed
header, which makes the separate "!al_entry->length" check redundant, so
drop it too.

🚨 CVE-2026-80870
In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Validate CRIU-restored IDs before idr_alloc
The KFD CRIU restore flow restores previously saved object IDs from
userspace.
For event restore:
kfd_criu_restore_event()
-> create_signal_event() / create_other_event()
-> allocate_event_notification_slot()
-> idr_alloc(..., *restore_id, *restore_id + 1, ...)
For BO restore:
criu_restore_memory_of_gpu()
-> idr_alloc(..., bo_priv->idr_handle, ...)
In both cases, the restored ID comes from userspace-provided CRIU data.
idr_alloc() expects the ID range values to fit within signed int
limits. If a restored ID is larger than INT_MAX, it can trigger a WARN
in the IDR layer.
A kernel WARN is undesirable because it prints a warning trace and may
cause a panic or reboot on systems with panic_on_warn enabled.
Smatch reported these paths as allowing unchecked userspace values to
reach idr_alloc().
Add INT_MAX validation before using restored IDs in:
- kfd_criu_restore_event()
- criu_restore_memory_of_gpu()
If the restored ID is invalid, return -EINVAL.
This prevents invalid restore data from reaching the IDR layer and
avoids WARN-triggering paths, while keeping valid restore behavior
unchanged.

This makes TCP state handling look at the wrong bytes when an IPv6

In the Linux kernel, the following vulnerability has been resolved:
ring-buffer: Fix event length with forced 8-byte alignment
When RB_FORCE_8BYTE_ALIGNMENT is true, rb_calculate_event_length()
reserves the space of event->array[0] for placing the data length and
rb_update_event() stores the data length in event->array[0]
accordingly. As a result the whole event length will add extra 4 bytes
for sizeof(event.array[0]) unconditionally.
But ring_buffer_event_length() only subtracts the
sizeof(event->array[0]) for events larger than RB_MAX_SMALL_DATA +
sizeof(event->array[0]). As a result, small events on architectures
with RB_FORCE_8BYTE_ALIGNMENT=true report a data length that is 4
bytes larger than expected.
To fix it, add the RB_FORCE_8BYTE_ALIGNMENT as a condition to subtract
the size of that length field whenever RB_FORCE_8BYTE_ALIGNMENT is
true.
This issue is observed in a riscv64 kernel with
CONFIG_HAVE_64BIT_ALIGNED_ACCESS set to y, when we run ftrace selftest

In the Linux kernel, the following vulnerability has been resolved:
ocfs2: fix circular locking dependency in ocfs2_dio_end_io_write
A circular locking dependency involves INODE_ALLOC_SYSTEM_INODE,
EXTENT_ALLOC_SYSTEM_INODE, and ORPHAN_DIR_SYSTEM_INODE.
1. ocfs2_mknod() acquires INODE_ALLOC then EXTENT_ALLOC.
2. ocfs2_dio_end_io_write() acquires EXTENT_ALLOC for unwritten
extents, then ORPHAN_DIR via ocfs2_del_inode_from_orphan() while still
holding EXTENT_ALLOC.
3. ocfs2_wipe_inode() acquires ORPHAN_DIR then INODE_ALLOC via
ocfs2_remove_inode.
Break the cycle in ocfs2_dio_end_io_write() by freeing the allocation
contexts (releasing EXTENT_ALLOC) before acquiring ORPHAN_DIR.

🚨 CVE-2026-80880
In the Linux kernel, the following vulnerability has been resolved:
IB/mlx5: Properly support implicit ODP rereg_mr
Due to all the child mkeys in the implicit ODP configuration we cannot
change anything in place for the parent mkey. Instead the whole thing
needs to be rebuilt if any change is requested. If the user does not
specify a translation then force the implicit values which will then fall
through the logic into mlx5_ib_reg_user_mr() to allocate a completely new
MR.
Since implicit children were also touching the mr->pd, this removes
another case where the access was racy.

🚨 CVE-2026-80883
In the Linux kernel, the following vulnerability has been resolved:
drm/tegra: gr2d/gr3d: Initialize address register map before HOST1X client is registered
The host1x_client_register() function is called just prior to register map
initialization loop, making the device available to userspace. This may
result in userspace attempting to submits a job before the register map is
initialized. Address this by moving register initialization before host1x
client registration.
