| In the Linux kernel, the following vulnerability has been resolved:
bpf: mark a NULL call argument precise
check_func_arg() allows bpf_register_is_null() for nullable arguments
w/o marking the underlying scalar register precise. Hence a checkpoint
created on such a path would prune against arbitrary scalar value.
check_helper_call() enforces second parameter of the
bpf_get_local_storage() to be zero, w/o marking the underlying scalar
register precise. Hence a checkpoint created on such a path would
prune against arbitrary scalar value.
Grouping these two into one patch, as they share the same fixes tag. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Mark NULL kptr stores precise
check_map_kptr_access() permits a scalar store into an untrusted kptr
field only when the register is known to contain zero. Unlike other
verifier checks whose outcome depends on a scalar value, it does not mark
that register precise.
A state checkpoint reached with an imprecise zero can therefore prune a
second path that reaches the store with an arbitrary nonzero scalar. The
program can write attacker-controlled bits into the kptr field and load
them back as a PTR_TO_BTF_ID.
Call mark_chain_precision() before accepting a known-zero register. This
forces state equivalence to compare its scalar range and makes the verifier
visit and reject a path carrying a nonzero value. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Cancel special fields when recycling rhtab elements
rhtab_map_update_existing() and rhtab_delete_elem() call
bpf_obj_free_fields() when replacing or deleting a value. These map
operations can run from BPF programs in NMI context, where releasing a
referenced kptr or another complex field is not generally safe.
Array and hash maps avoid that problem by cancelling only the asynchronous
fields which can be stopped safely in the caller context. Other ownership
state remains attached to the allocation until its memory allocator
destructor performs the final cleanup.
Use bpf_obj_cancel_fields() for the corresponding rhtab paths as well. This
cancels timers, workqueues, and task work while allowing rhtab_mem_dtor() to
release referenced kptrs when the allocation is eventually destroyed.

| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_nat_sip: rewind offset when NAT shrinks the packet
sashiko says:
If map_addr() changes the packet length, such as when the public NAT IP
string is shorter or longer than the internal IP, coff will still point to
the offset relative to the pre-mangled packet.
If the packet shrinks, coff could overshoot the correct position,
potentially causing the next ct_sip_parse_header_uri() call to silently
skip bytes and miss subsequent Contact headers. Could this lead to a
failure to NAT those subsequent headers and leak internal network details? |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix the possible bioc_list memory leak during error
There are two possible ways to leak bioc memory on
btrfs_ordered_extent::bioc_list:
- An error occurred for btrfs_insert_one_raid_extent()
Then the function btrfs_insert_raid_extent() immediately return
without freeing any bioc in the bioc_list.
- An ordered extent hit an IO error
In that case the ordered extent will have BTRFS_ORDERED_IOERR set, and
skip the call on btrfs_insert_raid_extent() completely.
Fix the problem by:
- Introduce a new helper, btrfs_cleanup_ordered_bioc_list()
Which will remove all bioc from the bioc_list, and release the bioc.
- Call the above helper for btrfs_insert_raid_extent()
So that the cleanup helper is always called no matter what.
- Call the above helper for btrfs_finish_one_ordered()
This is called just before the final release on the ordered extent.
This was reported by Sashiko when reviewing another patch. |
| In the Linux kernel, the following vulnerability has been resolved:
staging: rtl8723bs: fix xmit_frame/xmit_buf leaks on mgnt-frame error paths
issue_beacon(), issue_probersp() and issue_asocrsp() obtain a management
xmit_frame together with its xmit_buf from the driver's fixed-size
management-TX pools via alloc_mgtxmitframe(). On the normal path the frame
is handed to dump_mgntframe(), which transfers ownership and eventually
returns both objects to their pools (the frame and, for beacons, the buf
in rtl8723bs_mgnt_xmit(); other bufs via the pending-xmitbuf/TX-completion
path).
Several error/edge paths return early after a successful
alloc_mgtxmitframe() but before dump_mgntframe(), so ownership is never
transferred and neither object is freed:
- issue_beacon(): beacon larger than 512 bytes
- issue_probersp(): cur_network->ie_length > MAX_IE_SZ
- issue_probersp(): kzalloc() of the SSID scratch buffer fails
- issue_asocrsp(): pkt_type is neither ASSOCRSP nor REASSOCRSP
Because alloc_mgtxmitframe() removes the frame and buf from their free
lists (list_del_init) without placing them on any pending list, an
orphaned pair is on no list and referenced by nobody, so it is only
reclaimed at driver teardown. Repeated hits progressively exhaust the
management-TX pools until alloc_mgtxmitframe() returns NULL and the
interface can no longer send beacons or probe/assoc responses.
Free the frame and buffer on these paths, matching the existing correct
error handling in issue_assocreq(). |
| In the Linux kernel, the following vulnerability has been resolved:
usb: typec: ucsi: unregister debugfs entries on teardown
ucsi_register() creates per-instance debugfs entries, but
ucsi_unregister() keeps them around until ucsi_destroy().
Drivers like ucsi_glink that unregister/register the same UCSI
instance across remoteproc restart then try to create an already
existing debugfs directory and log:
debugfs: 'pmic_glink.ucsi.0' already exists in 'ucsi'
Unregister debugfs entries as part of ucsi_unregister(), and
clear ucsi->debugfs after freeing it so repeated unregister
paths remain safe. |

| A vulnerability was determined in Blosc C-Blosc2 up to 3.3.2. This impacts the function blosclz_decompress of the file blosc/blosclz.c of the component blosclz Decompression. Executing a manipulation can lead to integer overflow. The attack may be launched remotely. A high complexity level is associated with this attack. The exploitability is said to be difficult. Upgrading to version 3.3.3 will fix this issue. This patch is called fe2964d114d97847f56570a0ab2be2c57ccbeedc. The affected component should be upgraded. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Check ancestor frames for rbtree callbacks
bpf_rbtree_add() invokes its comparator while the caller holds the root
lock. The native insertion code retains raw parent and link pointers across
the callback, so the verifier prohibits unlocking, consuming tree nodes,
or changing RCU state from that callback.
in_rbtree_lock_required_cb() only checks the innermost verifier frame.
Static subprogram calls are permitted while holding a spin lock, and such a
call pushes a frame without in_callback_fn set. Consequently, all callback
restrictions disappear in the nested frame. The subprogram can unlock the
tree, remove and drop the node being compared, then relock. Native insertion
resumes with the stale parent pointer and links freed memory into the tree.
Walk all active frames for the rbtree callback instead. Benign static
subprograms remain permitted, while callback restrictions follow execution
into nested frames. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: don't rewrite bpf_fastcall patterns entered by a jump
mark_fastcall_pattern_for_call() must ensure that matched
"spill; call; fill" instruction series is not interrupted by a jump.
Otherwise the rewrite applied by bpf_remove_fastcall_spills_fills()
is not sound.
Record the instructions targeted by jumps in
insn_aux_data[*].jump_target when the CFG is built and use this flag
to stop growing a pattern at such an instruction. Jumps to the first
spill are fine.
Note that existing insn_aux_data[*].jmp_point field can't be reused,
as it marks subprogram return instructions. |
| In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Remove __counted_by from struct amdxdna_cmd_chain
struct amdxdna_cmd_chain contains a flexible array annotated with
__counted_by(command_count). Since the structure is stored in shared
AMDXDNA_BO_SHARE memory, userspace can modify command_count concurrently.
If command_count is changed to zero, the bounds check generated from
__counted_by may fail and trigger a kernel panic.
Remove __counted_by to avoid relying on the userspace-controlled
command_count for the flexible array bounds check. |
