| In the Linux kernel, the following vulnerability has been resolved:
net: systemport: Fix buffer overflow in bcm_sysport_get_stats()
When running on SYSTEMPORT Lite, certain statistics are unsupported and
skipped during bcm_sysport_get_stats(). The variable 'j' tracks the
compacted index into the destination data buffer, whereas 'i' iterates
over all elements in bcm_sysport_gstrings_stats.
Because the buffer allocated by ethtool is sized only according to
bcm_sysport_get_sset_count(), storing values at data[i] instead of
data[j] writes past the allocated array bounds, leading to memory
corruption.
Fix this by writing to data[j] instead of data[i]. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: backtrack_insn(): Handle ld_{abs,ind} subprog exit edge
Nicholas Carlini reported a bug in precision backtracking mechanism
for BPF_LD | BPF_{IND,ABS} instructions. These instructions are
modelled as two branches:
- fallthrough;
- implicit exit from current subprogram.
The implicit exit case was not handled by the backtrack_insn()
function. When backtracking such a path backtrack_insn() did not
call bt_subprog_enter(), which meant that backtracking continued
manipulating precision marks in a caller frame, while looking at
instructions in a callee frame.
This lead to segmentation faults during verification (see the
selftest), or unsound state pruning. |
| In the Linux kernel, the following vulnerability has been resolved:
net: bridge: use option bits for CFM/MRP frame handlers
CFM and MRP register a global br_frame_type whose hlist_node is linked
into the per-bridge frame_type_list when the first MEP/MRP instance is
created. Enabling the protocol on multiple bridges therefore inserts the
same node into multiple lists. Unregistering it on one bridge then
corrupts list state belonging to another.
These handlers can only be installed once per bridge, and they are
uncommon. Track their per-bridge enable state with net_bridge option
bits, which already live on the Rx hot cache line, and dispatch the
matching handler directly from the receive path. Check both bits
together first as an unlikely case.
Remove the generic frame_type_list and br_frame_type helpers, which
have had no other users since CFM and MRP were added. That shrinks
struct net_bridge by 8 bytes and drops the list walk from the fast
path. When neither protocol is compiled in, BR_CFM_MRP_OPTS is 0 and
the compiler prunes the branch. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: reject duplicate wiphy cipher suite entries
Duplicate entries in wiphy->cipher_suites do not describe any
additional capability, but cfg80211 currently accepts them and leaves
individual consumers to deal with them.
One such consumer is the WEXT compatibility code, which appends a WEP
key length for each WEP cipher entry it sees. Repeated WEP entries can
therefore overflow the fixed iw_range::encoding_size array returned by
SIOCGIWRANGE.
Reject duplicate cipher suite entries in wiphy_register() instead.
This keeps the cipher suite invariant in one place and makes malformed
wiphy descriptions fail early with -EINVAL, rather than relying on a
single cfg80211 user to handle duplicates correctly. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: uac: validate rate list length before storing
UAC1 and UAC2 configfs rate-list attributes parse a comma-separated
list of sampling rates and store each parsed value in fixed-size arrays.
The arrays have UAC_MAX_RATES entries, but the store paths do not check
that the input contains at most that many tokens before writing through
opts->name##s[i++].
Writing more than ten rates therefore writes past the end of the
p_srates[] or c_srates[] array in struct f_uac1_opts or struct
f_uac2_opts.
With CONFIG_UBSAN_BOUNDS enabled, writing an 11-entry rate list to the
UAC1 p_srate attribute reports:
UBSAN: array-index-out-of-bounds
drivers/usb/gadget/function/f_uac1.c:1669:1
index 10 is out of range for type 'int [10]'
__ubsan_handle_out_of_bounds.cold
f_uac1_opts_p_srate_store
configfs_write_iter
vfs_write
ksys_write
do_syscall_64
The same reproducer against the UAC2 p_srate attribute reports:
UBSAN: array-index-out-of-bounds
drivers/usb/gadget/function/f_uac2.c:2087:1
index 10 is out of range for type 'int [10]'
__ubsan_handle_out_of_bounds.cold
f_uac2_opts_p_srate_store
configfs_write_iter
vfs_write
ksys_write
do_syscall_64
Reject additional tokens once UAC_MAX_RATES entries have been parsed.
Also keep the original kstrdup() pointer for kfree(), because strsep()
advances the parsing cursor. Freeing the advanced cursor leaks the
original buffer on successful parses and can free an interior pointer on
some error paths. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix WARNING in bpf_tracing_link_release
The trampoline could be corrupted by the blindly
'tr->flags = BPF_TRAMP_F_TAIL_CALL_CTX' in verifier.
1. A fexit attached to a tail_call_reachable prog. 'tr->flags' became
'BPF_TRAMP_F_CALL_ORIG | BPF_TRAMP_F_TAIL_CALL_CTX'. And, the
trampoline would poke the target prog's nop insn using jmp insn instead
of call insn.
2. Another fexit loaded with the same tail_call_reachable prog target.
'tr->flags' became 'BPF_TRAMP_F_TAIL_CALL_CTX'.
3. Close the first fexit link. Due to no BPF_TRAMP_F_CALL_ORIG in
'tr->flags', the trampoline will fail to restore the prog's nop insn
using call insn.

| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix stride mismatch in mac_phy_caps_parse()
Currently, in ath12k_wmi_mac_phy_caps_parse(), kzalloc() sizes the
mac_phy_caps buffer as tot_phy_id * len, where len is clamped to
min(firmware_len, sizeof(struct ath12k_wmi_mac_phy_caps_params)). The
subsequent memcpy() destination advances by sizeof(full struct) per slot
via C pointer arithmetic, not by the clamped len. When firmware sends
short TLVs, the second and later slots are written past the end of the
allocation.
The reader in ath12k_pull_mac_phy_cap_svc_ready_ext() also indexes the
buffer with full-struct pointer arithmetic, so the allocation must match
that stride.
Fix by using kzalloc_objs(), which derives the element size from the
pointer type, making allocation size and pointer stride provably
consistent regardless of what len the firmware provides.

| In the Linux kernel, the following vulnerability has been resolved:
ocfs2/cluster: keep heartbeat local node stable
o2nm_node_local_store() handles local=0 by stopping o2net and setting
cl_local_node to O2NM_INVALID_NODE_NUM, but it leaves cl_has_local set.
That stale state makes o2nm_this_node() return 255, blocks a later local=1
attempt with -EBUSY, and can feed 255 to heartbeat users that call
o2nm_this_node() dynamically.
Clearing cl_has_local is required when the local node is reset. But
heartbeat threads can still be running at that point. They pin the local
node config item at startup, yet o2hb_do_disk_heartbeat() and thread
teardown re-read o2nm_this_node() for the local slot and for
o2nm_undepend_this_node(). Once local=0 has cleared the live local-node
state, those dynamic reads return O2NM_MAX_NODES, which is also the
invalid node number 255.
Store the local node number in the heartbeat region when the region
starts. Use that stable node for heartbeat slot writes/checks,
negotiation messages, and the final configfs undepend. Stop the heartbeat
loop when the current local node no longer matches the stored node, and
clear cl_has_local together with cl_local_node in the local=0 path so
nodemanager state matches node removal.

| In the Linux kernel, the following vulnerability has been resolved:
ocfs2: validate external xattr entries when reading metadata
ocfs2_validate_xattr_block() checks the xattr block header before the
block reaches higher-level xattr users, but it does not verify that a
non-indexed block's xh_count and entry offsets fit inside the block.
Indexed buckets likewise reach list/get consumers after ECC without an
entry-bounds check.
Use the flat xattr entry validator for non-indexed external xattr blocks,
and use a bucket-specific validator for indexed buckets at metadata read
time. The bucket validator keeps the entry array bounded by the first
bucket block while checking name/value offsets against the bucket block
they target.
Reject corrupted external xattr metadata before listxattr() or getxattr()
can walk out-of-range entry arrays or name/value offsets.
