| In the Linux kernel, the following vulnerability has been resolved:
ACPICA: Fix integer overflow in acpi_ex_opcode_3A_1T_1R() (mid_op)
Add overflow check for Index + Length to prevent integer overflow
when calculating the truncation length. This prevents negative
size parameter being passed to memcpy(). |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix invalid data access in ath11k_dp_rx_h_undecap_nwifi
In certain cases, hardware might provide packets with a
length greater than the maximum native Wi-Fi header length.
This can lead to accessing and modifying fields in the header
within the ath11k_dp_rx_h_undecap_nwifi() function for the
DP_RX_DECAP_TYPE_NATIVE_WIFI decap type and
potentially result in invalid data access and memory corruption.
Kernel stack is corrupted in: ath11k_dp_rx_h_undecap+0x6b0/0x6b0 [ath11k]

Add a sanity check before processing the SKB to prevent invalid
data access in the undecap native Wi-Fi function for the
DP_RX_DECAP_TYPE_NATIVE_WIFI decap type.
This adapted from the discussion/patch of the ath12k driver [1].

| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/pm: bound pp_dpm_set_pp_table() memcpy
The powerplay path allocates hardcode_pp_table once with kmemdup(...,
soft_pp_table_size). memcpy(..., size) used the sysfs store count (up to
PAGE_SIZE) with no upper bound, causing heap overflow. Reject
writes where size exceeds soft_pp_table_size. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: fix buffer overflow during vBIOS update
Clamp the buffer postion to write by setting the bin attribute
to the maximum buffer size so that VFS layer will block the
out-of-bounds accessing. |

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:
wifi: iwlwifi: mvm: fix out-of-bounds tid_data access in BA notif
mvmsta->tid_data was indexed by the TFD loop counter 'i' instead of
the actual TID value 'tid'. This writes lq_color into a random tid_data
slot unrelated to the BA entry.
Since multi-TID blockack is not really in use, 'i' was always 0 and no
harm was done.
Add a out-of-bound check before accessing the array. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7915: bound the device EEPROM address before the EFUSE copy
mt7915_mcu_get_eeprom() copies a fixed EFUSE block into the driver's
dev->mt76.eeprom.data buffer at the offset reported by the MCU response
(res->addr, a device-controlled __le32) without checking it against the
buffer size. A malicious or malfunctioning device can report an arbitrary
address and drive a 16-byte out-of-bounds write past eeprom.data.
Reject a response whose address would place the copy outside eeprom.data
before deriving the destination pointer. Devices that echo the requested
in-bounds offset are unaffected. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: bound the device EEPROM address before the EFUSE copy
mt7996_mcu_get_eeprom() derives the destination of the EFUSE/EXT block
copy from the address reported by the MCU response (event->addr, a
device-controlled __le32) and clamps only the copy length, never the
destination offset into dev->mt76.eeprom.data. A malicious or
malfunctioning device can report an arbitrary address and drive an
out-of-bounds write of up to MT7996_EXT_EEPROM_BLOCK_SIZE bytes past
eeprom.data.
Reject a response whose address would place the copy outside eeprom.data
before deriving the destination pointer. Devices that echo the requested
in-bounds offset are unaffected. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: ISO: fix malformed ISO_END/CONT handling
Core specification (Part C vol 4 sec 5.4.5) does not exclude empty
ISO_CONT, ISO_END packets. We currently reject them if they are last.
If controller sends malformed sequence
ISO_START -> rx_len = 4, ISO_CONT skb->len 4, ISO_START
that ends payload in ISO_CONT, we leak conn->rx_skb. If controller sends
too long ISO_END, we panic on skb_put. If controller sends too short
ISO_END we accept it.
Fix by marking unfinished ISO_START via conn->rx_skb != NULL. Check
skb->len properly before skb_put. Combine the ISO_CONT/END code paths
as they require the same initial checks. Reject too short ISO_END
packets. |
| In the Linux kernel, the following vulnerability has been resolved:
drop_monitor: fix size calculations for 64-bit attributes
net_dm_packet_report_fill() and net_dm_hw_packet_report_fill() use
nla_put_u64_64bit() to append 64-bit attributes (NET_DM_ATTR_PC and
NET_DM_ATTR_TIMESTAMP).
On 32-bit architectures without CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS,
nla_put_u64_64bit() may append a 4-byte NET_DM_ATTR_PAD attribute for
64-bit alignment.
However, net_dm_packet_report_size() and net_dm_hw_packet_report_size()
used nla_total_size(sizeof(u64)) instead of nla_total_size_64bit(sizeof(u64)),
budgeting 12 bytes instead of up to 16 bytes.
This under-estimation of SKB size can lead to an skb_over_panic() when
__nla_reserve() or skb_put() is subsequently called.
Fix this by using nla_total_size_64bit(sizeof(u64)) in both size calculations. |

| In the Linux kernel, the following vulnerability has been resolved:
ethtool: cmis: require exact CDB reply length
Malicious SFP module could respond with rpl_len longer than
what cmis_cdb_process_reply() expected, leading to OOB writes.
Malicious HW is a bit theoretical but some modules may just
be buggy and/or the reads may occasionally get corrupted,
so let's protect the kernel.
The existing check protects from short replies. We need to
protect from long ones, too. All callers that pass a non-zero
rpl_exp_len cast the reply payload to a fixed-layout struct
and read fields at fixed offsets, with no version negotiation
or short-reply handling:
- cmis_cdb_validate_password()
- cmis_cdb_module_features_get()
- cmis_fw_update_fw_mng_features_get()
so let's assume that responses longer than expected do not
have to be handled gracefully here. Add a warning message
to make the debug easier in case my understanding is wrong...
Note that page_data->length (argument of kmalloc) comes from
last arg to ethtool_cmis_page_init() which is rpl_exp_len.
Note2 that AIs also like to point out overflows in args->req.payload
itself (which is a fixed-size 120 B buffer, on the stack),
but callers should be reading structs defined by the standard,
so protecting from requests for more data than max seem like
defensive programming. |

| GNU coreutils unexpand is vulnerable to a heap-based buffer overflow due to an integer overflow during buffer allocation when processing large tab stop (-t) values. The multiplication used to calculate the allocation size can wrap around, resulting in an undersized buffer.
When processing crafted input, subsequent writes exceed the allocated memory, leading to an out‑of‑bounds heap write.
When running GNU coreutils unexpand with attacker-provided large tab stop (-t) arguments, this behavior leads to a crash and potentially achieve a heap write primitive depending on memory layout.
This issue has been fixed in the commit b60a159fdc5bfcf9988d3a4cb6f53abe8ad5d35d |
| Pexip Infinity before 38.2, plus 39.0, 39.1 and 40.0, is affected by improper input validation that allows a remote attacker to execute code remotely as an unprivileged user on a Pexip Infinity Conferencing Node. |
| An unprivileged, memory-protected ThreadX module can have the kernel read and write memory at addresses of its choosing, in privileged mode, and can use that to clear the MPU enable bit and remove its own isolation boundary.
The Module Manager decided whether a privileged service could dereference an object address a module named by asking only whether that address fell outside the module. The manager's object pool is outside every module, so the test was satisfied by an address shifted into the interior of one of the module's own privileged allocations, which denotes no object at all. The bytes such an address presents as a control block are bytes the module put there through ordinary create and set services, so the control block ID at the front of them could be made to read as any type the module chose, and the `_txe_` layer's ID test then agreed. The reported chain uses that to reach a privileged `memset` across an attacker-chosen range. |
