| In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix next_buffer UAF and NextCommand bounds in compound PDUs
Fix several related bounds checking and pointer lifecycle issues in
receive_encrypted_standard()'s handling of compound encrypted frames:
- Clear next_buffer after assigning it to server->bigbuf. A stale
next_buffer pointer can lead to a use-after-free on subsequent
error paths.
- Update pdu_length to the decrypted plaintext size (buf_size). Using
the pre-decryption length allows NextCommand to point into stale
ciphertext residue.
- Reject next_cmd values smaller than MID_HEADER_SIZE(server).
- Fix an integer overflow in the upper bound check by verifying
pdu_length - next_cmd < MID_HEADER_SIZE(server), ensuring the
trailing slice is large enough for a header. |

xfrm: iptfs: fix stack OOB read in iptfs_skb_reset_frag_walk()
iptfs_skb_reset_frag_walk() advances to the fragment containing @offset
with an unbounded loop:
while (offset >= walk->past + walk->frags[walk->fragi].len)
walk->past += walk->frags[walk->fragi++].len;
walk->fragi is advanced and walk->frags[walk->fragi] is dereferenced
without ever checking fragi against walk->nr_frags. When the requested
offset is at or beyond the total length spanned by the walk's fragments,
fragi runs past nr_frags and off the end of the fixed-size on-stack
frags[MAX_SKB_FRAGS + 1] array, reading out-of-bounds stack memory.
The two callers behave differently: iptfs_skb_add_frags() already guards
against this with
if (!walk->nr_frags ||
offset >= walk->total + walk->initial_offset)
return len;
but iptfs_skb_can_add_frags() has no such guard and calls
iptfs_skb_reset_frag_walk() unconditionally, so it performs the
out-of-range walk. Its own "fragi < walk->nr_frags" bound check runs only
afterwards, too late to prevent the read.
This is reachable from the receive path: a crafted IP-TFS (AGGFRAG)
payload delivered to an IPTFS SA drives iptfs_reassem_cont() ->
iptfs_skb_can_add_frags() with an offset past the fragment total, e.g.:
BUG: KASAN: stack-out-of-bounds in iptfs_skb_reset_frag_walk+0x235/0x250

ip_rcv+0x278/0x2d0 net/ipv4/ip_input.c:612
Give iptfs_skb_can_add_frags() the same up-front guard that
iptfs_skb_add_frags() already has, so the walk is never entered with an
out-of-range offset. When it triggers, the caller falls back to the
existing linearize-and-copy path, which is safe. |

| In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Avoid integer underflow in EOP ring size calculation.
The low 6 bits of cp_hqd_eop_control store the base-2 logarithm
of the EOP ring size. This was calculated as
order_base_2(q->eop_ring_buffer_size / 4) - 1
But order_base_2 can in theory return 0, so this could underflow
(although in practice the ring buffer size cannot be less than 4096).
Change this to
order_base_2(q->eop_ring_buffer_size / 8)
using properties of logarithms.
Also add to the above comment to make the mathematics more clear.

| GNU Aspell contains an out-of-bounds read vulnerability in ReadOnlyDict::load() in readonly_ws.cpp. When loading a binary .rws dictionary file, it uses offset fields from the file header as byte indices into a heap buffer without validating their bounds. An attacker can trigger this by convincing a user to run aspell with a crafted dictionary file supplied through --master, --dict-dir, or configuration options, leading to heap memory disclosure or a denial of service via application crash.
This issue was fixed in commit 941953b25031bc9104e83f58e138a664b8dedc3f which will be released in version 0.60.8.3. |
| Microsoft UFO is an open-source framework for intelligent automation across devices and platforms. Prior to 3.0.9, the execute_command tool in ufo/client/mcp/http_servers/linux_mcp_server.py treats sort and uniq as read-only commands while the free-form command parameter can select their file-output forms. An authenticated caller can use sort -o or the optional second uniq operand to create or overwrite files writable by the UFO server process without shell metacharacters, because the allowed binary opens the destination itself and the argument policy does not reject the operation. This can corrupt configuration or other writable data and disrupt the service, but the demonstrated primitive does not directly disclose files or establish arbitrary code execution. This issue is fixed in version 3.0.9. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix potential OOB read in smb3_enum_snapshots()
If snapshot_array_size is smaller than GMT_TOKEN_SIZE,
smb3_enum_snapshots() sets ret_data_len to
sizeof(struct smb_snapshot_array) without verifying the actual length
of the server's reply.
Because SMB2_ioctl() places no lower bound on the server-supplied
OutputCount and allocates retbuf to exactly that length, a short reply
results in ret_data_len exceeding the size of retbuf. The subsequent
copy_to_user() then reads past the end of retbuf, leaking adjacent slab
memory to userspace. The subsequent clamp check is ineffective as it
only reduces ret_data_len.
Fix this by rejecting replies shorter than
sizeof(struct smb_snapshot_array) with -EIO. Note that the bound is set
to the 12-byte struct size rather than the 16-byte
MIN_SNAPSHOT_ARRAY_SIZE defined in MS-SMB2 3.3.5.15.1, because 12 bytes
is exactly what copy_to_user() attempts to read. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix OOB struct field reads in move_smb2_ea_to_cifs()
In move_smb2_ea_to_cifs(), the while (src_size > 0) loop condition is
insufficient. It allows iteration to continue even if the remaining
src_size is too small to contain a complete smb2_ea_info structure.
Consequently, reads of ea_name_length and ea_value_length can occur
out-of-bounds.
Fix this by ensuring src_size >= sizeof(*src) before attempting to read
any structure fields. Additionally, reject any next_entry_offset that is
smaller than sizeof(*src) or that would advance the pointer beyond the
available buffer.
Note that for calls where the server returns a malformed EA list, the
error returned to userspace changes from -ENODATA (getxattr) or
-ERANGE (listxattr) to -EIO. This correctly signals a server protocol
error rather than misleadingly indicating "attribute not present" or
"output buffer too small". |
| Payload is a free and open source headless content management system. In versions from 3.0.0 before 3.90.0 and canary versions before 4.0.0-canary.34, a malformed multipart request body can cause multipart Content-Type processing to take an extremely long time, resulting in uncontrolled resource consumption. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34. |
| Payload is a free and open source headless content management system. In @payloadcms/plugin-form-builder versions before 3.90.0 and canary versions before 4.0.0-canary.34, an attacker can craft a form submission that executes code remotely on the server. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34. |

| Quasar Framework is a framework for building high-performance Vue.js user interfaces. Prior to 2.22.0, the SSR-only getHead() serializer in ui/src/plugins/meta/Meta.js used getAttr() to interpolate values supplied through useMeta() into title, meta, link, and script markup without HTML text or quoted-attribute encoding. injectServerMeta() appended that output to the raw server-rendered response. An attacker who can influence dynamic page metadata, such as a post title, product name, excerpt, or display name, can terminate the intended HTML context and inject executable markup before hydration. The client-side apply() path is not affected because it uses DOM APIs that encode attributes. This issue is fixed in version 2.22.0. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix server->total_read for compound encrypted PDUs
In receive_encrypted_standard(), server->total_read is left at the
full decrypted frame size when walking sub-PDUs of a compound encrypted
frame. As a result, cifs_handle_standard() passes this full size
to smb2_check_message(), causing the PDU length guards to incorrectly
validate the entire compound frame instead of the current sub-PDU.
This allows truncated non-last sub-PDUs to bypass length validation,
leading to out-of-bounds reads in smb2_get_data_area_len().
Fix this by setting server->total_read to the true length of the
current sub-PDU: next_cmd for non-last sub-PDUs, and the remaining
pdu_length for the last one. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: libipw: reject TKIP frames without a full MIC
libipw_michael_mic_verify() assumes that an skb contains an eight-byte
Michael MIC. A short TKIP frame makes the unsigned payload length wrap,
causing michael_mic() to read past the skb.
Check that the MIC is present before verifying it, and use the existing
MICHAEL_MIC_LEN constant for all MIC lengths in the verifier. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix reparse buffer bounds in cifs_query_reparse_point()
In cifs_query_reparse_point(), the start >= end check before casting to
struct reparse_data_buffer * only ensures the start pointer is within the
response. It fails to verify that there is enough space remaining for the
fixed 8-byte header of the structure.
If a server provides a DataOffset that leaves less than 8 bytes remaining,
the check passes, but subsequent reads of ReparseTag and ReparseDataLength
will occur out-of-bounds.
Fix this by ensuring the remaining space is at least the size of the
reparse_data_buffer structure before accessing its fields. |
| NVIDIA TensorRT contains a vulnerability where an attacker can cause an out of bounds read. A successful exploit of this vulnerability may lead to denial of service. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btmtksdio, btmtkuart: validate WMT event length before struct access
btmtksdio.c and btmtkuart.c cast a received WMT event straight to
struct btmtk_hci_wmt_evt and read its op/flag fields without checking
the event is long enough to contain them, unlike btmtk.c. The
FUNC_CTRL case then further casts to struct btmtk_hci_wmt_evt_funcc
and reads its 2-byte status field, again without a length check.
Firmware that sends a short or malformed WMT event makes both drivers
read past the end of the received SKB.
Mirror btmtk.c: validate the base WMT header with skb_pull_data()
before touching any of its fields, and when a FUNC_CTRL event turns
out to be the short, header-only form (a plain enable/disable ack
with no status word), decode the result from the header's own flag
byte instead (0 = success, otherwise failure).
Verified setup on MT7920, MT7921, MT7922 and MT7925: no regression. |
| Twisted is an event-based framework for internet applications, supporting Python 3.6+. In 25.5.0 and earlier, wildcardToRegexp() in twisted/mail/imap4.py translates the IMAP asterisk and percent wildcards but passes all other characters from an authenticated client's LIST or LSUB pattern directly to re.compile(), allowing nested or otherwise expensive regular expression constructs to cause catastrophic backtracking when matched against mailbox names. Because Twisted uses a cooperative single-threaded reactor, the blocking match suspends all server input and output for the duration of the match. No fixed release is available as of this review. |
