| In the Linux kernel, the following vulnerability has been resolved:
wifi: wl1251: validate packet IDs before indexing tx_frames
wl1251_tx_packet_cb() uses the firmware completion ID directly to index
the fixed 16-entry wl->tx_frames[] array. The ID is a raw u8 from the
completion block, and the callback does not currently verify that it
fits the array before dereferencing it.
Reject completion IDs that fall outside wl->tx_frames[] and keep the
existing NULL check in the same guard. This keeps the fix local to the
trust boundary and avoids touching the rest of the completion flow. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: validate bsscfg indices in IF events
brcmf_fweh_handle_if_event() validates the firmware-provided interface
index before it touches drvr->iflist[], but it still uses the raw
bsscfgidx field as an array index without a matching range check.
Reject IF events whose bsscfg index does not fit in drvr->iflist[]
before indexing the interface array.

| In the Linux kernel, the following vulnerability has been resolved:
net: sched: act_csum: validate nested VLAN headers
tcf_csum_act() walks nested VLAN headers directly from skb->data when an
skb still carries in-payload VLAN tags. The current code reads
vlan->h_vlan_encapsulated_proto and then pulls VLAN_HLEN bytes without
first ensuring that the full VLAN header is present in the linear area.
If only part of an inner VLAN header is linearized, accessing
h_vlan_encapsulated_proto reads past the linear area, and the following
skb_pull(VLAN_HLEN) may violate skb invariants.
Fix this by requiring pskb_may_pull(skb, VLAN_HLEN) before accessing and
pulling each nested VLAN header. If the header still is not fully
available, drop the packet through the existing error path. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: xt_multiport: validate range encoding in checkentry
ports_match_v1() treats any non-zero pflags entry as the start of a
port range and unconditionally consumes the next ports[] element as
the range end.
The checkentry path currently validates protocol, flags and count, but
it does not validate the range encoding itself. As a result, malformed
rules can mark the last slot as a range start or place two range starts
back to back, leaving ports_match_v1() to step past the last valid
ports[] element while interpreting the rule.
Reject malformed multiport v1 rules in checkentry by validating that
each range start has a following element and that the following element
is not itself marked as another range start. |
| In the Linux kernel, the following vulnerability has been resolved:
ALSA: fireworks: bound device-supplied status before string array lookup
The status field in an EFW response is a 32-bit value supplied by the
firewire device. efr_status_names[] has 17 entries so a status value
outside that range goes off into the weeds when looking at the %s value.
Even worse, the status could return EFR_STATUS_INCOMPLETE which is
0x80000000, and is obviously not in that array of potential strings.
Fix this up by properly bounding the index against the array size and
printing "unknown" if it's not recognized. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: renesas_usb3: validate endpoint index in standard request handlers
The GET_STATUS and SET/CLEAR_FEATURE handlers extract the endpoint
number from the host-supplied wIndex without any sort of validation.
Fix this up by validating the number of endpoints actually match up with
the number the device has before attempting to dereference a pointer
based on this math.
This is just like what was done in commit ee0d382feb44 ("usb: gadget:
aspeed_udc: validate endpoint index for ast udc") for the aspeed driver. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: require 3 sub-authorities before reading sub_auth[2]
parse_dacl() compares each ACE SID against sid_unix_NFS_mode and on
match reads sid.sub_auth[2] as the file mode. If sid_unix_NFS_mode is
the prefix S-1-5-88-3 with num_subauth = 2 then compare_sids() compares
only min(num_subauth, 2) sub-authorities so a client SID with
num_subauth = 2 and sub_auth = {88, 3} will match.
If num_subauth = 2 and the ACE is placed at the very end of the security
descriptor, sub_auth[2] will be 4 bytes past end_of_acl. The
out-of-band bytes will then be masked to the low 9 bits and applied as
the file's POSIX mode, probably not something that is good to have
happen.
Fix this up by forcing the SID to actually carry a third sub-authority
before reading it at all. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/damon/core: validate damos_quota_goal->nid for node_memcg_{used,free}_bp
Users can set damos_quota_goal->nid with arbitrary value for
node_memcg_{used,free}_bp. But DAMON core is using those for NODE-DATA()
without a validation of the value. This can result in out of bounds
memory access. The issue can actually triggered using DAMON user-space
tool (damo), like below.
$ sudo mkdir /sys/fs/cgroup/foo
$ sudo ./damo start --damos_action stat --damos_quota_interval 1s \
--damos_quota_goal node_memcg_used_bp 50% -1 /foo
$ sudo dmseg
[...]
[ 524.181426] Unable to handle kernel paging request at virtual address 0000000000002c00
Fix this issue by adding the validation of the given node id. If an
invalid node id is given, it returns 0% for used memory ratio, and 100%
for free memory ratio. |

btrfs: fix EEXIST abort due to non-consecutive gaps in chunk allocation
I have been observing a number of systems aborting at
insert_dev_extents() in btrfs_create_pending_block_groups(). The
following is a sample stack trace of such an abort coming from forced
chunk allocation (typically behind CONFIG_BTRFS_EXPERIMENTAL) but this
can theoretically happen to any DUP chunk allocation.

| In the Linux kernel, the following vulnerability has been resolved:
net: usb: cdc_ncm: add ndpoffset to NDP16 nframes bounds check
cdc_ncm_rx_verify_ndp16() validates that the NDP header and its DPE
entries fit within the skb. The first check correctly accounts for
ndpoffset:
if ((ndpoffset + sizeof(struct usb_cdc_ncm_ndp16)) > skb_in->len)
but the second check omits it:
if ((sizeof(struct usb_cdc_ncm_ndp16) +
ret * (sizeof(struct usb_cdc_ncm_dpe16))) > skb_in->len)
This validates the DPE array size against the total skb length as if
the NDP were at offset 0, rather than at ndpoffset. When the NDP is
placed near the end of the NTB (large wNdpIndex), the DPE entries can
extend past the skb data buffer even though the check passes.
cdc_ncm_rx_fixup() then reads out-of-bounds memory when iterating
the DPE array.
Add ndpoffset to the nframes bounds check and use struct_size_t() to
express the NDP-plus-DPE-array size more clearly. |
| The MongoDB C Driver's legacy GridFS API accepts malformed file metadata from the database without adequate validation. Crafted documents in a GridFS collection may cause any application that reads those files via the legacy API to either crash (via a division-by-zero) or silently leak process memory contents (via an out-of-bounds read). |
| In the Linux kernel, the following vulnerability has been resolved:
media: dvb-net: fix OOB access in ULE extension header tables
The ule_mandatory_ext_handlers[] and ule_optional_ext_handlers[] tables
in handle_one_ule_extension() are declared with 255 elements (valid
indices 0-254), but the index htype is derived from network-controlled
data as (ule_sndu_type & 0x00FF), giving a range of 0-255. When
htype equals 255, an out-of-bounds read occurs on the function pointer
table, and the OOB value may be called as a function pointer.
Add a bounds check on htype against the array size before either table
is accessed. Out-of-range values now cause the SNDU to be discarded. |
| In the Linux kernel, the following vulnerability has been resolved:
mshv_vtl: Fix vmemmap_shift exceeding MAX_FOLIO_ORDER
When registering VTL0 memory via MSHV_ADD_VTL0_MEMORY, the kernel
computes pgmap->vmemmap_shift as the number of trailing zeros in the
OR of start_pfn and last_pfn, intending to use the largest compound
page order both endpoints are aligned to.
However, this value is not clamped to MAX_FOLIO_ORDER, so a
sufficiently aligned range (e.g. physical range
[0x800000000000, 0x800080000000), corresponding to start_pfn=0x800000000
with 35 trailing zeros) can produce a shift larger than what
memremap_pages() accepts, triggering a WARN and returning -EINVAL:
WARNING: ... memremap_pages+0x512/0x650
requested folio size unsupported
The MAX_FOLIO_ORDER check was added by
commit 646b67d57589 ("mm/memremap: reject unreasonable folio/compound
page sizes in memremap_pages()").
Fix this by clamping vmemmap_shift to MAX_FOLIO_ORDER so we always
request the largest order the kernel supports, in those cases, rather
than an out-of-range value.
Also fix the error path to propagate the actual error code from
devm_memremap_pages() instead of hard-coding -EFAULT, which was
masking the real -EINVAL return. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ipa: fix event ring index not programmed for IPA v5.0+
For IPA v5.0+, the event ring index field moved from CH_C_CNTXT_0 to
CH_C_CNTXT_1. The v5.0 register definition intended to define this
field in the CH_C_CNTXT_1 fmask array but used the old identifier of
ERINDEX instead of CH_ERINDEX.
Without a valid event ring, GSI channels could never signal transfer
completions. This caused gsi_channel_trans_quiesce() to block
forever in wait_for_completion().
At least for IPA v5.2 this resolves an issue seen where runtime
suspend, system suspend, and remoteproc stop all hanged forever. It
also meant the IPA data path was completely non functional. |
| vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, sandboxed code can call Buffer.alloc() with an arbitrary size to allocate memory directly on the host heap. Because Buffer.alloc is a synchronous C++ native call, vm2's timeout option cannot interrupt it. A single request can exhaust host memory and crash the process with a FATAL ERROR: Reached heap limit. This vulnerability is fixed in 3.11.0. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: fix 22000 series SMEM parsing
If the firmware were to report three LMACs (which doesn't
exist in hardware) then using "fwrt->smem_cfg.lmac[2]" is
an overrun of the array. Reject such and use IWL_FW_CHECK
instead of WARN_ON in this function. |

LoongArch: Make cpumask_of_node() robust against NUMA_NO_NODE
The arch definition of cpumask_of_node() cannot handle NUMA_NO_NODE -

drm/amdgpu: validate doorbell_offset in user queue creation
amdgpu_userq_get_doorbell_index() passes the user-provided
doorbell_offset to amdgpu_doorbell_index_on_bar() without bounds
checking. An arbitrarily large doorbell_offset can cause the
calculated doorbell index to fall outside the allocated doorbell BO,
potentially corrupting kernel doorbell space.
Validate that doorbell_offset falls within the doorbell BO before
computing the BAR index, using u64 arithmetic to prevent overflow.
