| In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: validate EHT MLE before MLD ID read
cfg80211_gen_new_ie() copies ML probe response elements from
the parent frame when the parent EHT multi-link element has an
MLD ID matching the nontransmitted BSSID index.
The code only checked that the extension element had more than
one byte before calling ieee80211_mle_get_mld_id(). That helper
assumes a BASIC MLE with enough common info and documents that
callers must first use ieee80211_mle_type_ok().
Attack chain:
malicious AP sends a short EHT MLE in an MBSSID beacon.
cfg80211_inform_bss_frame_data() stores the copied IE buffer.
cfg80211_parse_mbssid_data() builds the nontransmitted BSS IE.
cfg80211_gen_new_ie() sees the EHT MLE in the parent frame.
ieee80211_mle_get_mld_id() then reads past the IE boundary.
Validate the MLE type and size before reading the MLD ID. This
matches the contract required by the MLE helper and rejects the
short element before any internal MLE fields are accessed. |

octeontx2-pf: fix SQB pointer leak on init failure
otx2_init_hw_resources() initializes SQ aura and pool resources before
several later setup steps. On failure, err_free_sq_ptrs only frees SQB
pages, leaving the per-SQ sqb_ptrs arrays behind.
Use otx2_free_sq_res() for the SQ unwind path and let it free sqb_ptrs
even when sq->sqe has not been allocated yet.
The bug was first flagged by an experimental analysis tool we are
developing for kernel memory-management bugs while analyzing
v6.13-rc1. The tool is still under development and is not yet publicly
available. Manual inspection confirms that the bug is still
present in v7.1.1.
An x86_64 allyesconfig build showed no new warnings. As we do not have an
OcteonTX2 PF device and the corresponding AF mailbox setup to test with,
no runtime testing was able to be performed. |
| siyuan versions <= 3.7.3 (fixed in v3.7.4) contain a server-side template injection vulnerability in the attribute-view Template calculation feature (introduced in v3.7.0-beta.1). The feature's template engine uses Sprig's unmodified function map, which still exposes the env, expandenv, and getHostByName functions that were removed elsewhere for CVE-2024-55660. A local, unauthenticated attacker (the kernel binds to 127.0.0.1 by default with no per-UID access control) can inject a malicious Template calculation formula to read environment variables belonging to the account running siyuan — including from a separate, unprivileged OS account — and to perform DNS lookups from the server's network position. |
| In the Linux kernel, the following vulnerability has been resolved:
s390/diag: Add missing array_index_nospec() call to memtop_get_page_count()
'level' is user space controlled and used to read from an array. Add the
missing array_index_nospec() call to prevent speculative execution. |
| In the Linux kernel, the following vulnerability has been resolved:
dm: avoid leaking the caller's thread keyring via the table device file
The refactoring in commit a28d893eb327 ("md: port block device access to file")
accidentally causes the caller's thread keyring to be kept alive long
beyond the caller's lifetime.
As a result, "cryptsetup luksSuspend" silently fails to wipe the
LUKS volume key from memory.
In detail: "cryptsetup luksOpen" uses its supposedly ephemeral thread
keyring to pass the volume key to the kernel. dm-crypt's
crypt_set_keyring_key() copies the key material into its own
crypt_config structure and then drops its own reference to the key in
the keyring with key_put().
With this fix, restoring pre-v6.9 behavior, the copy in the thread
keyring is then promptly garbage collected, such that exactly one copy
of the volume key remains. This single copy is correctly wiped from
memory on "cryptsetup luksSuspend".
Without this fix, the thread keyring and the volume key in it remains.
This second copy is only freed on "luksClose". "luksSuspend" neither
knows about this copy nor has any way to remove it, so the key remains
recoverable from RAM after a suspend that is documented to have wiped it.
This fix should not introduce new security problems, as the code is
anyway gated by CAP_SYS_ADMIN. The device-mapper core, not the calling
task, is the legitimate owner of this long-lived file. |
| In the Linux kernel, the following vulnerability has been resolved:
Input: ims-pcu - validate control endpoint type
The driver currently assumes that the first endpoint of the control
interface is an interrupt IN endpoint without verifying it. A malicious
device could provide a different endpoint type, which would then be
passed to usb_fill_int_urb(), potentially leading to kernel warnings
or undefined behavior.
Verify that the control endpoint is an interrupt IN endpoint. |
| In the Linux kernel, the following vulnerability has been resolved:
netdev-genl: report NAPI thread PID in the caller's pid namespace
netdev_nl_napi_fill_one() reports the NAPI kthread PID in NETDEV_A_NAPI_PID
using task_pid_nr(), which returns the PID in the initial pid namespace.
NETDEV_CMD_NAPI_GET does not have GENL_ADMIN_PERM and the netdev genl family
is netnsok, so a caller in a child pid namespace can issue it. That caller
then sees the kthread's global PID, even though the kthread is not visible
in its pid namespace, where the value should be 0.
Translate the PID through the caller's pid namespace, the same way commit
3799c2570982 ("io_uring/fdinfo: translate SqThread PID through caller's
pid_ns") did for the io_uring SQPOLL thread. The doit and dumpit paths both
run synchronously in the caller's context, so task_active_pid_ns(current) is
the caller's pid namespace. |
| In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Use caller client for debug BO sync
amdxdna_drm_sync_bo_ioctl() looks up args->handle in the ioctl caller's
drm_file. For SYNC_DIRECT_FROM_DEVICE, it then calls
amdxdna_hwctx_sync_debug_bo(), but passes abo->client.
amdxdna_hwctx_sync_debug_bo() uses the passed client both as the handle
namespace for debug_bo_hdl and as the owner of the hardware context xarray.
Those must match the file that supplied args->handle. The BO's stored
client pointer is object state, not the ioctl context.
Pass filp->driver_priv instead, matching the original handle lookup. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: validate attribute values on lookup
ntfs_attr_find() and ntfs_external_attr_find() check that generic
resident attribute values fit in their attribute records and that
fixed-size resident values are large enough. For variable-length resident
formats, however, the fixed part is not enough: embedded length fields
can still point callers past the resident value.
A crafted image can set a small resident $FILE_NAME value_length while
leaving file_name_length large. Callers then trust file_name_length and
read past the resident value when converting or comparing the name. This
was reproduced with a crafted image under KASAN as a slab-out-of-bounds
read from the kmalloc-1k MFT record copy. The stack included
ntfs_lookup(), ntfs_iget(), ntfs_read_locked_inode(), ntfs_attr_name_get(),
ntfs_ucstonls(), and utf16s_to_utf8s().
Add a shared attribute value validator and use it before a lookup path
can return an attribute, including the AT_UNUSED enumeration case where
callers inspect returned attributes directly. The helper validates
resident value bounds, minimum resident value sizes, variable-length
$FILE_NAME fields, and non-resident mapping-pairs metadata that was
previously checked separately in both lookup paths.
This also preserves the intended resident @val matching semantics in the
external attribute lookup path. The old duplicated validation block
overwrote the actual resident value length with the type-specific minimum
length before comparing @val, so variable-length resident values could
fail to match even when the bytes were identical. Keep the comparison on
the actual value length, and make ntfs_attrlist_entry_add() compare
resident attributes with lowest_vcn zero instead of reading the
non-resident union member after a successful resident match.
Reject non-resident $FILE_NAME records too: the format requires
$FILE_NAME to be resident and callers treat returned records as resident. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: topology: validate vendor array size before parsing
sof_parse_token_sets() reads array->size while iterating over topology
private data. The loop condition only checks that some data remains, so a
malformed topology with a truncated trailing vendor array can make the
parser read the size field before a full vendor-array header is available.
Validate that the remaining private data contains a complete
snd_soc_tplg_vendor_array header before reading array->size.
The declared array size check also needs to remain signed. asize is an int,
but sizeof(*array) has type size_t, so comparing them directly promotes
negative asize values to unsigned and lets them pass the check,
as reported in the stable review thread reference below.
Cast sizeof(*array) to int when validating the declared array size. This
rejects negative, zero and otherwise too-small sizes before the parser
dispatches to the tuple-specific code. |
| In the Linux kernel, the following vulnerability has been resolved:
platform/x86: ISST: Restore SST-PP control to all domains
The SST-PP control offset is only restored to power domain 0 after
resume. During suspend, control values are read and stored for all
power domains.
Use pd_info->sst_base instead of power_domain_info->sst_base, which
only points to power domain 0 base address. |
| In the Linux kernel, the following vulnerability has been resolved:
sunrpc: fix uninitialized xprt_create_args structure
The xprt_create_args structure is allocated on the stack without
initialization in rpc_sysfs_xprt_switch_add_xprt_store(). While some
fields are manually populated, critical fields like srcaddr, bc_xps,
and flags contain uninitialized stack garbage.
This can lead to:
1. Kernel panic when xs_setup_xprt() dereferences garbage srcaddr
2. Information leak if srcaddr points to sensitive stack data
3. Unpredictable behavior if flags has random bits set
The fix is to zero-initialize the structure to ensure all unused
fields are NULL/0, preventing the transport setup code from acting
on garbage data. |

mtd: spi-nor: swp: Improve locking user experience
In the case of the first block being locked (or the few first blocks),
if the user want to fully unlock the device it has two possibilities:
- either it asks to unlock the entire device, and this works;
- or it asks to unlock just the block(s) that are currently locked,
which fails.
It fails because the conditions "can_be_top" and "can_be_bottom" are
true. Indeed, in this case, we unlock everything, so the TB bit does not
matter. However in the current implementation, use_top would be true (as
this is the favourite option) and lock_len, which in practice should be
reduced down to 0, is set to "nor->params->size - (ofs + len)" which is
a positive number. This is wrong.
An easy way is to simply add an extra condition. In the unlock() path,
if we can achieve the same result from both sides, it means we unlock
everything and lock_len must simply be 0. A comment is added to clarify
that logic. |
| In the Linux kernel, the following vulnerability has been resolved:
ocfs2: reject dinodes with non-canonical i_mode type
Patch series "ocfs2: harden inode validators against forged metadata", v2.
This series adds three structural checks to OCFS2 dinode validation so
malformed on-disk fields are rejected before ocfs2_populate_inode() copies
them into the in-core inode.
The checks cover:
- i_mode values whose type bits do not name a canonical POSIX file
type;
- non-device dinodes whose id1.dev1.i_rdev field is non-zero; and
- non-inline dinodes that claim non-zero i_size while i_clusters is
zero, covering directories unconditionally and regular files on
non-sparse volumes.
The normal read path reports these through ocfs2_error(), matching the
existing suballoc-slot, inline-data, chain-list, and refcount checks. The
online filecheck path uses the same structural predicates but keeps its
own reporting contract, returning OCFS2_FILECHECK_ERR_INVALIDINO instead
of calling ocfs2_error().
This patch (of 3):
ocfs2_validate_inode_block() currently accepts any non-zero i_mode value.
ocfs2_populate_inode() then copies that mode verbatim into inode->i_mode
and dispatches on i_mode & S_IFMT to the file/dir/symlink/special_file
iops; an unrecognised type falls through to ocfs2_special_file_iops and
init_special_inode().
Reject dinodes whose type bits do not name one of the seven canonical
POSIX file types. Use fs_umode_to_ftype(), the same generic file-type
conversion helper OCFS2 already uses for directory entries, so the
accepted inode type set matches the kernel file-type vocabulary instead of
open-coding a local switch.
Apply the same structural check to the online filecheck read path.
filecheck keeps its own error namespace, so it reports malformed i_mode
through the filecheck logger and OCFS2_FILECHECK_ERR_INVALIDINO instead of
calling ocfs2_error(), but it must not allow a malformed dinode to proceed
into ocfs2_populate_inode(). |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: validate index entries on reading
Validate index entries immediately after reading an index root or index
block from disk. This eliminates repeated checks in lookup and readdir,
and reduce the risk of missing checks in those paths. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: validate index block header more strictly
Modify ntfs_index_block_inconsisent() to perform stricter validation of
INDEX_HEADER geometry in INDX blocks, and update
ntfs_lookup_inode_by_name() to use that function to validate INDX
blocks. |

netfilter: nf_conncount: fix zone comparison in tuple dedup
The "already exists" dedup logic in __nf_conncount_add() decides
whether a connection has already been counted and can be skipped instead
of incrementing the connlimit count. It compares the conntrack zone of a
list entry with the zone of the connection being added using
nf_ct_zone_id() and nf_ct_zone_equal(), passing conn->zone.dir or
zone->dir as the direction argument.
Those helpers take enum ip_conntrack_dir values: IP_CT_DIR_ORIGINAL is 0
and IP_CT_DIR_REPLY is 1. However, zone->dir is a u8 bitmask:
NF_CT_ZONE_DIR_ORIG is 1, NF_CT_ZONE_DIR_REPL is 2 and
NF_CT_DEFAULT_ZONE_DIR is 3. Passing that bitmask as the enum direction
shifts the meaning of every non-zero value. An ORIG-only zone passes 1
and is tested as REPLY, while REPL-only and default zones pass 2 or 3 and
test bits beyond the valid direction range. In those cases
nf_ct_zone_id() can fall back to NF_CT_DEFAULT_ZONE_ID instead of using
the real zone id, so different zones can be treated as equal and dedup
collapses to tuple equality alone.
nf_conncount stores and compares the original-direction tuple for a
connection. If an skb already has an attached conntrack entry,
get_ct_or_tuple_from_skb() explicitly copies
ct->tuplehash[IP_CT_DIR_ORIGINAL].tuple, regardless of the packet's
ctinfo. Therefore the zone comparison in the tuple dedup path must use
IP_CT_DIR_ORIGINAL as well; the zone direction bitmask describes where a
zone id applies, not which direction this conncount tuple represents.
Fix the two dedup comparisons by passing IP_CT_DIR_ORIGINAL directly.
Do not special-case NF_CT_DEFAULT_ZONE_DIR and do not compare raw zone
ids: using the existing helpers with IP_CT_DIR_ORIGINAL preserves the
direction-aware NF_CT_DEFAULT_ZONE_ID fallback. A default bidirectional
zone contains the ORIG bit, so it naturally returns the real zone id;
reply-only zones continue to fall back for original-direction tuple
comparisons. |

ASoC: SDCA: Validate written enum value in ge_put_enum_double()
ge_put_enum_double() passes the user-supplied enumeration index
item[0] to snd_soc_enum_item_to_val() without checking it against the
number of items in the enum:
ret = snd_soc_enum_item_to_val(e, item[0]);
snd_soc_enum_item_to_val() indexes the heap-allocated e->values[] array
with that index (e->values is set from a devm_kcalloc() of e->items
entries), so a control write with an out-of-range item[0] reads past the
end of the values buffer. The bounds check in
snd_soc_dapm_put_enum_double() only runs afterwards, so it does not
prevent the read here.
Reject an out-of-range item before using it, matching the other enum put
handlers.
This issue was pointed out by the Sashiko AI review bot while reviewing a
related enum-validation series:

drm/xe/pf: Don't attempt to process FAST_REQ or EVENT relays
Currently defined VF/PF relay actions use regular REQUEST messages
only and the PF shouldn't attempt to handle FAST_REQUEST nor EVENT
messages as this would result in breaking the VFPF ABI protocol
and also might trigger an assert on the PF side.
