| In the Linux kernel, the following vulnerability has been resolved:
bnxt_en: Bound SW TPA IDs to prevent crashes
FW supports up to 1024 concurrent TPAs, so the FW TPA ID is in the range
0..1023 (see commit ec4d8e7cf024 ("bnxt_en: Add TPA ID mapping logic for
57500 chips.")). bnxt_alloc_agg_idx is intended to wrap the FW ID down to a
software ID which is used to index rxr->rx_tpa, and to generate a mapping
between FW IDs and the wrapped software ID.
On a 57608 with firmware version 233, the firmware advertises 32
concurrent TPAs. As of the commit under fixes, bp->max_tpa on this NIC
is set to 32.
If the software ID from bnxt_alloc_agg_idx is above 31, this results in
an invalid address being loaded on this line:
tpa_info = &rxr->rx_tpa[agg_id];
because rx_tpa is allocated with only bp->max_tpa (32) entries. Writes
to tpa_info later in the code are out of bounds.
This bug results in a crash at boot:

This stack trace is from a crash triggered when an out of bounds rx_tpa
is dereferenced. The invalid write mentioned above is silent in this
particular crash.
Fix this by allocating rx_tpa with bp->max_tpa rounded up to the next
power of 2 (bp->max_tpa_roundup_size) entries and masking the FW TPA ID
with that size, so the wrapped ID can never index past the end of the
array. |
| Ghidra versions 11.2 through 12.1.4 contain a heap out-of-bounds read vulnerability in StringManager::getCodepoint when decoding multi-byte UTF-8, UTF-16, or UTF-32 characters without validating remaining buffer length. Attackers can craft malicious binaries with constant byte stores ending in multi-byte lead units to trigger out-of-bounds reads that crash the decompiler or leak adjacent heap memory into decompiled output. |
| In the Linux kernel, the following vulnerability has been resolved:
xfs: fix the rtrmap and rtrefcount _maxlevels_ondisk functions
The _maxlevels_ondisk functions are used to compute the size of
in-memory btree cursors for each btree type. Unfortunately, LOLLM
noticed that the rtrmap and rtrefcount versions of these functions
forget to account for the inode root, which means that we could access
beyond the end of the cursor given a sufficiently large btree. Fix
this. |
| In the Linux kernel, the following vulnerability has been resolved:
net: dsa: bcm_sf2: bound the CFP rule dump by the caller's buffer size
bcm_sf2_cfp_rule_get_all() walks the whole cfp.unique bitmap into
rule_locs[] without consulting nfc->rule_cnt, which is how many entries
the caller had room for. ETHTOOL_GRXCLSRLALL requires no CAP_NET_ADMIN
and the ioctl sizes the buffer from the rule_cnt userspace passes in, so
once an admin has installed CFP rules any user can ask for fewer slots
than there are rules and run off the end of the allocation. A rule_cnt
of 0 leaves the buffer pointer NULL and the walk dereferences it. |
| Netdata is an open source observability tool. Prior to 2.10.4, an authenticated child agent can send an oversized DIMENSION SLOT value that str2ull_encoded passes to pluginsd_rrddim_put_to_slot in src/plugins.d/pluginsd_internals.h without an upper bound. prd_array_create in src/database/rrdset-pluginsd-array.h can then wrap the size_t allocation calculation while retaining the original large array size, causing the subsequent initialization loop to write beyond the undersized heap allocation and crash the parent agent. This issue is fixed in version 2.10.4 and nightly build 2.10.0-782-nightly. |
| Lantronix SLC8000/SLC9000 before firmware v9.7.0.2, EMG8500/EMG7500 before firmware v9.7.0.1, and all firmware versions of SLB882/SLCx-03/SLCx-02 contain a stack-based buffer overflow vulnerability that allows authenticated attackers to potentially execute arbitrary code by exploiting an undocumented mfc eeprom read command that copies unbounded user input into a bounded stack buffer before passing it to a system() call. Attackers can authenticate as any user to the terminal or CLI interface and supply an oversized input to trigger the overflow, potentially achieving complete loss of confidentiality, integrity, and availability on the affected device and impacting downstream serial-attached devices. |
| MCP Atlassian is a Model Context Protocol (MCP) server for Atlassian products (Confluence and Jira). Prior to 0.22.0, Jira search accepts a forbidden project clause because it checks only for the presence of project syntax, Confluence search uses an incomplete case-sensitive space check, and Jira board APIs omit project-filter enforcement. These paths expose issues, boards, or pages outside JIRA_PROJECTS_FILTER or CONFLUENCE_SPACES_FILTER when the operator credentials have broader access. The advisory traces the vulnerable input and processing flow through jira_search, confluence_search, get_board_issues, get_agile_boards, JIRA_PROJECTS_FILTER, and CONFLUENCE_SPACES_FILTER, which identify the affected entry points, controls, and code paths. This issue is fixed in version 0.22.0. |
| Catalyst::Seal versions before 0.03 for Perl allow one request to disable a path or route a later one past an authorization check via a dispatch memo keyed on the request path alone.
Catalyst::Seal replaces the dispatcher's prepare_action with a version that memoises how a path resolved: which dispatch type matched, at which level, and what was left over as arguments. The key is the request path and nothing else. Action roles that match on the method, content type, scheme or query make that resolution depend on state the key does not carry, so the memo answers for a request it was not built from.
A path that resolves to no action is memoised as well, and replaying that entry returns without consulting any dispatch type, so no action is set and the request fails. A GET of a path whose action is declared POST-only therefore disables that path for every later request, the correct POST included. An entry that did resolve replays the level the earlier descent reached. Where a POST-only action sits below a shallower action on the same path, a GET memoises the shallow route, and a later POST is dispatched there with an auto() guarding the deeper controller never running.
The memo is cleared only when an action is registered, which happens at setup, so an entry lasts for the life of the process, and its cap of 2048 entries bounds how many paths one caller can disable. In the configuration measured, the misroute lands on the less privileged action, so it is an authorization check not running rather than a privilege gain. |
| In the Linux kernel, the following vulnerability has been resolved:
media: verisilicon: rockchip: reject AV1 frames exceeding the tile capacity
rockchip_vpu981_av1_dec_set_tile_info() indexes the tile group entry
array by tile1 * tile_cols + tile0, reading up to tile_cols * tile_rows
entries, lays out one descriptor per tile in the AV1_MAX_TILES tile_info
buffer, and programs the real tile_cols / tile_rows into the hardware.
The tile group entry control is a dynamic array sized to the number of
entries userspace submitted, independent of tile_cols / tile_rows, so a
frame that claims more tiles than entries reads past the array. A frame
that claims more than AV1_MAX_TILES tiles also leaves the hardware
programmed for more tiles than the descriptor buffer holds.
Reject both in prepare_run(): tile_cols * tile_rows must not exceed the
submitted entry count or AV1_MAX_TILES. The entry count is read via
v4l2_ctrl_find() (ctrl->elems). This mirrors the bound the mediatek AV1
decoder already enforces. |
| In the Linux kernel, the following vulnerability has been resolved:
mptcp: close race between scheduler and state change
The mptcp scheduler may race with subflow sockets state change: data
transmission on the selected socket may fail and a later release could
try to use mss_now reset to 0 for a divide operation.
Address the issue by explicitly checking for the critical scenario. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Validate BSG request_len before reading vendor_cmd[]
The FC BSG transport allocates job->request via memdup_user() using the
exact user-supplied request_len. For FC_BSG_HST_VENDOR,
fc_bsg_host_dispatch() only guarantees request_len covers msgcode and
vendor_id; it does not account for the vendor_cmd[] flexible array.
qla2xxx then reads the command selector vendor_cmd[0] and, in several
sub-handlers, vendor_cmd[1]/[2] or structures overlaid on the vendor
command area without verifying request_len. A caller holding
CAP_SYS_RAWIO can submit a short request whose vendor_id matches the
host, triggering out-of-bounds heap reads (KASAN-detectable, and able to
mis-select a command or panic).
Add a central guard in qla2x00_process_vendor_specific() so the selector
is always in bounds, restrict the early vendor_cmd[0] read in
qla24xx_bsg_request() to sufficiently long vendor messages, and add
request_len checks to the sub-handlers that read further:
qla24xx_proc_fcp_prio_cfg_cmd(), qla2x00_process_loopback(),
qla84xx_reset(), qla84xx_updatefw(), qla2x00_read_optrom(),
qla2x00_update_optrom(), qlafx00_mgmt_cmd() and
qla28xx_validate_flash_image(). |
| In the Linux kernel, the following vulnerability has been resolved:
iommu/amd: Fix ineffective error check in nested domain allocation
amd_iommu_pdom_id_alloc() returns an int: a domain ID on success, or the
negative errno from ida_alloc_range() when the ID space is exhausted or
memory is short. amd_iommu_alloc_domain_nested() stores that return value
in gdom_info->hdom_id, which is a u32, and only then tests it:
gdom_info->hdom_id = amd_iommu_pdom_id_alloc();
if (gdom_info->hdom_id <= 0) {
The assignment discards the sign, so -ENOSPC becomes 0xffffffe4 and the
test never fires. The nested domain is then set up with a host domain ID
that was never allocated, instead of the allocation failing with -ENOSPC.
Keep the value in an int, test it there, and store it only once it is
known to be valid, which is what the other amd_iommu_pdom_id_alloc()
callers already do. |
| In the Linux kernel, the following vulnerability has been resolved:
ipv6: sr: restore network header before routing and forwarding
ipv6_srh_rcv() runs with skb->data at the Segment Routing Header (SRH)
while skb_network_header() points at the IPv6 header.
When segments_left > 0, ipv6_srh_rcv() previously restored the skb->data
position by pushing sizeof(struct ipv6hdr), assuming the SRH immediately
followed the fixed IPv6 header. If another extension header (such as a
Hop-by-Hop options header) precedes the SRH, skb_network_offset()
remained negative.
This led to two problems:
1. During ip6_route_input(), fib6_rules_early_flow_dissect() invokes
__skb_flow_dissect() which passes the negative skb_network_offset()
to flow dissection, breaking BPF and C flow dissector logic.
2. If forwarded via ip6_forward() or redirected via act_mirred, downstream
handlers (like sch_fragment() or neighbour output) pass the negative
offset as an unsigned length, triggering OOB memcpy or buffer overflows.
Fix this by pushing -skb_network_offset(skb) before routing, ensuring
skb_network_offset(skb) is 0 for route lookup / flow dissection as well as
downstream forwarding. On the loopback path, pull skb_transport_offset(skb)
to restore skb->data to the SRH before looping back. |
| In the Linux kernel, the following vulnerability has been resolved:
accel: ethosu: Don't read the U65 rounding mode as a storage mode
Bits 15:14 of NPU_SET_{IFM,OFM}_PRECISION select the activation storage
mode on U85 only. On U65 the same field holds the rounding mode, and the
command stream parser has read it as a storage mode since the driver was
added.
That went unnoticed while unknown values fell through the switch, but
now that they are rejected, every U65 command stream that asks for
natural rounding (2) fails CMDSTREAM_BO_CREATE with -EINVAL. Mesa emits
it for average pooling, concatenation, split, unpack, strided slice, LUT
and argmax, which is 72 failures of the Teflon test suite on an i.MX93.
Truncating rounding (1) is misread as well: it picks the two-tile
address path and computes a bogus feature map size from tile bases the
command stream never set.
Read the field as a storage mode only on the hardware where it is one. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: xusbatm: don't rely on id table pointer arithmetic
The current code is broken when dynamic ID is involved; in such cases
usb_device_id parameter of probe lives on the heap and the pointer
arithmetic will get an index that is wildly out of bound. xusbatm
initialize the USB device IDs dynamically so it can just use driver_info
too.
Even with conversion, xusbatm still cannot support dynamic IDs, so also set
no_dynamic_id. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: reject out-of-bounds DataOffset in CIFSSMBRead()
The SMB1 synchronous read helper CIFSSMBRead() validates the server's
DataLength against CIFSMaxBufSize and the caller's count, but never
validates DataOffset. The copy source is formed as
&pSMBr->hdr.Protocol + le16_to_cpu(pSMBr->DataOffset)
and memcpy()'d for DataLength bytes with no check that the
[DataOffset, DataOffset + DataLength) range lies within the response
actually received from the server.
A malicious or compromised SMB1 server can return a response carrying
an in-range DataLength and a large DataOffset, driving the source
pointer past the end of the response buffer. The memcpy() then copies
adjacent kernel heap into the caller's read buffer (information
disclosure), or reads unmapped memory and oopses (denial of service).
SMB1 is not negotiated by default; reaching this code requires an
explicit vers=1.0 mount.
Both DataOffset and the received response length recorded in
rsp_iov.iov_len are relative to the start of the SMB header, so reject
the response unless DataOffset + DataLength fits within that length,
using overflow-safe arithmetic, before forming the source pointer.
The response length has been validated by the previous patch, so the
DataOffset and DataLength fields can be read safely here.
While here, make data_length unsigned. It holds a length derived from
unsigned on-the-wire fields and is only ever compared against unsigned
quantities; print it with %u accordingly, and add __func__ to the
cifs_dbg() calls in this function. |
| In the Linux kernel, the following vulnerability has been resolved:
perf: RISC-V: store available counter mask as bitmap
The available-counter mask was a single unsigned long, but iteration
uses RISCV_MAX_COUNTERS, which is 64. On RV32 that reads past the object.
Filling with an unsigned-long bit at index 32 and above is also wrong.
Use DECLARE_BITMAP and set_bit/bitmap helpers. Walk each bitmap word
into CFG_MATCH when checking events, when allocating an index, and when
stopping all counters. Set the counter base to i times BITS_PER_LONG.
Share the CFG_MATCH ecall through a small helper so the 32-bit argument
split is not duplicated. On qemu-system-riscv32 the probe bitmap has bits
above XLEN set, so the first word alone is not enough.

| In the Linux kernel, the following vulnerability has been resolved:
xfs: initialise args->total for parent pointer updates
xfs_parent_da_args_init() builds an xfs_da_args from a zeroed
xfs_parent_args (kmem_cache_zalloc), leaving args->total == 0.
xfs_da_grow_inode_int() treats that field as a running block reservation
and subtracts from it; because it is an xfs_extlen_t (uint32_t), the
first attr-fork growth wraps it to ~0U. That defeats the free-space
check in xfs_alloc_space_available(), and when it coincides with an AG
that has exactly zero available blocks the allocation is clamped to
maxlen 0 and returns -ENOSPC, which xfs_defer_finish_noroll() escalates
to a filesystem shutdown.
Set args->total the way the log recovery path does
(xfs_attri_recover_work(), xfs_attr_item.c:706), in the add and replace
paths that can grow the fork. Removals and lookups never grow it, so
they leave the field alone, matching that switch. |

smb: client: fix one-byte OOB read in smb2_parse_native_symlink()
When parsing a share-root relative native symlink, memcpy copies
smb_target+1 (skipping the leading separator) but uses
strlen(smb_target)+1 as the length, reading one byte past the
allocated buffer.

rockchip_vpu981_av1_dec_set_tile_info() divides context_update_tile_id by
tile_info->tile_cols and writes one descriptor per tile into the tile_info
