| In the Linux kernel, the following vulnerability has been resolved:
ntfs3: fix out-of-bounds read in decompress_lznt
decompress_lznt() does not validate array index bounds before accessing
the decompression table. A corrupted NTFS3 image with invalid compressed
data can trigger an out-of-bounds read.
Add index bounds checking to prevent the OOB access. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: core: Fix OOB read in hid_get_report for numbered reports
When a caller passes a size of 0 to hid_report_raw_event() for a
numbered report, the function originally called hid_get_report() before
performing any size validation.
Inside hid_get_report(), if the report is numbered (report_enum->numbered
is true), it unconditionally dereferences data[0] to extract the report ID.
With a size of 0, this results in an out-of-bounds read or kernel panic.
Fix this by moving the numbered report size validation check before the
call to hid_get_report(), ensuring that size is at least 1 before
dereferencing the data pointer. |
| In the Linux kernel, the following vulnerability has been resolved:
apparmor: fix potential UAF in aa_replace_profiles
The function aa_replace_profiles was accessing udata->size after calling
aa_put_loaddata(udata), causing a potential UAF.
Fixed this by saving the size to a local variable before dropping the
reference. |
| In the Linux kernel, the following vulnerability has been resolved:
octeontx2-af: npc: Fix size of entry2cntr_map
KASAN prints below splat. This is caused by allocating counter for
reserved mcam entry for cpt 2nd pass entry. But mcam->entry2cntr_map
is not allocated for reserved entries.

| In the Linux kernel, the following vulnerability has been resolved:
cxl: Fix CXL_HEADERLOG_SIZE to match RAS Capability size
The CXL r4.0 8.2.4.17.7 RAS Capability Structure has total length 0x58
bytes (CXL_RAS_CAPABILITY_LENGTH); the Header Log occupies the trailing
64 bytes at offset 0x18. CXL_HEADERLOG_SIZE was defined as SZ_512,
eight times the actual on-device size.
header_log_copy() reads CXL_HEADERLOG_SIZE_U32 (128) dwords from the
RAS capability iomap, overrunning the 88-byte mapping by 448 bytes.
The cxl_aer_uncorrectable_error trace event memcpy()s CXL_HEADERLOG_SIZE
(512) bytes from its source. For the CPER caller the source is
struct cxl_ras_capability_regs::header_log[16] (64 bytes) embedded in a
stack-local cxl_cper_prot_err_work_data, so the memcpy reads 448 bytes
of kernel stack into the trace event ring buffer where userspace can
read it via tracefs.
Set CXL_HEADERLOG_SIZE to 64 and derive CXL_HEADERLOG_SIZE_U32 from it,
bringing all iomap readers into agreement on 16 dwords. Userspace tools
such as rasdaemon have grown a dependency on the buggy 512-byte (128 u32)
header_log layout in the cxl_aer_uncorrectable_error trace event. Add
CXL_HEADERLOG_TRACE_SIZE_U32 = 128 and use it for the trace event
__array and its memcpy to preserve that ABI. Both callers now pass a
zero-filled u32[CXL_HEADERLOG_TRACE_SIZE_U32] staging buffer with only
the first CXL_HEADERLOG_SIZE_U32 (16) entries populated from hardware;
the remaining 112 u32s are zero-padded, keeping the 512-byte trace ring
buffer layout intact.

| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: LAG, MPESW, Fix missing complete() on devcom error
mlx5_mpesw_work() returned without calling complete() when
mlx5_lag_get_devcom_comp() returned NULL. A caller that queued the
work and waited on mpesww->comp would block indefinitely.
Funnel the early-return path through a new "complete" label so the
waiter is always woken. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: validate resident attribute lists and harden the validator
A base inode's $ATTRIBUTE_LIST is sanity-checked by load_attribute_list()
only on the non-resident path; ntfs_read_locked_inode() copies a *resident*
attribute list into ni->attr_list with a plain memcpy() and no validation
at all. Every subsequent walk of ni->attr_list --
ntfs_external_attr_find(), ntfs_inode_attach_all_extents() and
ntfs_attrlist_need() -- then trusts the entries are well-formed and reads
attr_list_entry fixed-header fields
(lowest_vcn at offset 8, mft_reference at offset 16, and the name) with
bounds that assume validation already happened. A crafted resident
attribute list therefore reaches those walks unvalidated and can drive
out-of-bounds reads of the attribute-list buffer.
load_attribute_list() itself reads ale->name_offset (offset 7),
ale->mft_reference (offset 16) and the name length under only an
"al < al_start + size" bound, so its own validation loop can over-read the
fixed header of a truncated trailing entry by a few bytes.
Factor the per-entry validation into ntfs_attr_list_entry_is_valid(),
which requires each entry's fixed header (offsetof(struct
attr_list_entry, name)) to be in range before any field is dereferenced,
that ale->length is a multiple of 8 covering the fixed header plus the
name, and that the entry is in use and carries a live MFT reference.
ntfs_attr_list_is_valid() walks the buffer with it and checks the entries
tile it exactly. Use the list validator in load_attribute_list()
(replacing the open-coded loop, closing its own over-read) and on the
resident path in ntfs_read_locked_inode() (which previously skipped
validation entirely); patches 2/3 reuse the per-entry helper at the other
two attribute-list walks. |
| Subject::new_for_owner() in the zbus_polkit crate encodes the uid entry of a unix-process polkit subject as an unsigned 32-bit integer (D-Bus type u), whereas the org.freedesktop.PolicyKit1.Authority interface specifies a signed 32-bit integer (D-Bus type i). Because of this type mismatch, polkit silently discards the caller-supplied UID and instead determines the subject's owner itself by looking up the PID in /proc, a lookup that is inherently subject to a time-of-check/time-of-use race.
Consequently, an application that passes a UID obtained from a trustworthy source — for example SO_PEERCRED Unix socket peer credentials — in order to defend against PID reuse receives no protection, and the supplied UID has no effect on the authorization decision. A local unprivileged attacker who can cause an authorized process to terminate and then win the race to have their own process assigned the same PID can be authorized under the identity of the terminated process, bypassing the polkit authorization check and performing actions the attacker is not entitled to.
This issue affects zbus_polkit before 5.1.0. |

| Klever-Go is the Go implementation of the Klever blockchain protocol. Prior to 1.7.19, processPercentageRoyaltiesTransfer in core/kapp/accounts/accounts.go calls SubFromBalance after the split loop and after the royaltiesToPay <= 0 early return. computeSplitRoyalties rejects only when splitToPay > royaltiesToPay, so a valid PercentTransferPercentage = 10000 split consumes exactly 100 percent of the royalty pool, sets royaltiesToPay to zero, and returns before the source account is debited. The split recipient receives the full royaltyAmount while the sender pays nothing and the supply counter is not updated, allowing unbounded off-the-books inflation of the transferred KDA. A KDA owner must configure a TransferPercentage royalty with a 100 percent split, after which any holder's transfer of the asset triggers the mint; the sibling processFixedRoyaltiesTransfer path is not affected because it debits the source before distribution. This issue is fixed in version 1.7.19. |
| Uninitialized resource in ANGLE in Google Chrome on on Windows prior to 152.0.7977.65 allowed a remote attacker to obtain cross-origin data via a crafted HTML page. (Chromium security severity: Medium) |
| MariaDB Connector/Node.js is used to connect applications developed on Node.js to MariaDB and MySQL databases. Prior to 3.2.4, 3.3.3, 3.4.6, and 3.5.3, MariaDB Connector/Node.js permits SQL injection when attacker-controlled Buffer parameters are escaped client-side under the big5, gbk, sjis, cp932, or gb18030 client character sets. PacketOutputStream.writeBufferEscape in lib/io/packet-output-stream.js escaped bytes without the charset-aware getMbRecognizer logic in lib/misc/charset-mb.js. The server SQL lexer runs my_ismbchar before escape processing, so an attacker-controlled lead byte can consume the inserted 0x5C backslash as a multibyte trail byte and leave the following 0x27 quote unescaped, terminating the string literal and allowing arbitrary SQL. The default utf8mb4 character set and parameters sent through the execute binary prepared-statement path are not affected. Successful exploitation can expose or modify data available to the database account. This issue is fixed in versions 3.2.4, 3.3.3, 3.4.6, and 3.5.3. |
