CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
NFSv4/pnfs: key the data server cache on the NFS version
nfs4_pnfs_ds_add() keys the per-net data server cache on the multipath
address set alone, and struct nfs4_pnfs_ds records no version. That
suffices for the files layout driver, which always connects with version
4, but flexfiles takes its version tuple from GETDEVICEINFO per device,
and one address can legitimately serve both NFSv3 and NFSv4.
Two deviceids on one address with different ds_versions[0].version
therefore share a single nfs4_pnfs_ds, and whichever mirror connects
first pins ds_clp to its own version. The other one is handed that
client anyway, so it selects rpc_call_ops for a version the connection
does not speak, and the mismatched sequence-slot handling dereferences
NULL.
Add the version to the cache key so the two cannot alias, giving each
version its own nfs4_pnfs_ds and connection while both mirrors stay
usable. Only the major version is compared, since that is what selects
rpc_call_ops and rpc_ops; v4.0 and v4.1 keep sharing a client. The files
layout driver passes the 4 it already hardcodes at connect time. |
| In the Linux kernel, the following vulnerability has been resolved:
s390/bpf: Replace ly instruction with llgf
cpu_nr is a 32 bit value and BPF_REG_0 is a 64 bit register, when ly loads
the cpu_nr into BPF_REG_0 it does not zero the upper bits, but llgf does. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: fix off-by-one page overflow in ntfs_decompress()
The per-token range check in ntfs_decompress() uses
if (cb >= cb_sb_end || dp_addr > dp_sb_end)
break;
so dp_addr == dp_sb_end falls through to the symbol copy
`*dp_addr++ = *cb++`, writing one byte past the destination page. Since
NTFS_SB_SIZE == PAGE_SIZE the destination is a single page, so the byte
lands in the adjacent page, and *dest_ofs is left one past the sub-block
end (the later `*dest_ofs &= ~PAGE_MASK` then yields 1, not 0, so the page
is never finalized and later sub-blocks keep writing further past it). A
corrupted compressed $DATA attribute thus produces a bounded run of
out-of-bounds writes when the file is read.
Break as soon as dp_addr reaches dp_sb_end; a full sub-block still
completes, as its final copy advances dp_addr to exactly dp_sb_end. |
| In the Linux kernel, the following vulnerability has been resolved:
hinic3: Fix skb linearization mismatch and drop skb when skb_checksum_help() failed
Previously, hinic3_send_one_skb() cached the skb fragment count before
calling hinic3_tx_offload(). If hinic3_tx_csum() falls back to
skb_checksum_help() for unsupported tunnel packets, the skb may be
linearized. Continuing to build the TX descriptor with the stale
fragment count leads to a descriptor mismatch, which can trigger
out-of-bounds DMA reads or IOMMU faults.
Furthermore, the old code ignored the return value of skb_checksum_help(),
transmitting corrupted packets with incomplete checksums upon failure.
Fix this by:
1. Moving the hinic3_tx_offload() call before calculating 'num_sge' to
ensure the correct fragment count is used if the SKB is linearized.
2. Propagating skb_checksum_help() errors and returning
HINIC3_TX_OFFLOAD_INVALID to properly drop the skb. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix UAF in bpf_trampoline_multi_attach_free on update failure
When bpf_trampoline_update() fails before modify_fentry_multi()/
unregister_fentry_multi() is called, cur_image is unchanged
(cur_image == old_image) and ftrace still calls into it. Freeing
old_image in that case causes a UAF.
Only free old_image when it differs from cur_image. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btnxpuart: Validate the FW dump header length
nxp_process_fw_dump() pulls the ACL header off the frame and then reads
seq_num and buf_len from a struct nxp_fw_dump_hdr placed at skb->data,
without checking that the ACL payload is long enough to contain it.
h4_recv_buf() collects HCI_ACL_HDR_SIZE bytes of header followed by the
number of payload bytes named in that header, so skb->len is 4 + dlen
with dlen supplied by the controller and possibly smaller than the 8
byte dump header, or zero. A short frame with connection handle 0xfff
therefore reads both fields from beyond the received data.
Beyond the read itself, buf_len is what terminates a dump: a value of
zero makes the driver call hci_devcd_complete() and reset the
controller, so a truncated frame can end a dump early.
Use skb_pull_data() to validate and pull the FW dump header before
accessing its fields. Warn and reject the chunk if the header is
truncated. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Check load-acquire src ptr type before the load
check_atomic_load() calls check_load_mem() before atomic_ptr_type_ok().
For a load-acquire that fetches into its own source register (dst_reg ==
src_reg), check_load_mem() overwrites src_reg's type with the type of the
loaded value, so the subsequent atomic_ptr_type_ok() no longer sees the
source pointer and fails to reject the disallowed types (ctx, pkt,
flow_keys, sock).
Since bpf_convert_ctx_accesses() does not rewrite atomic loads, the raw
access to the underlying kernel object is left in place. The destination
type is taken from the ctx access itself, so a load-acquire of the sk
field of struct __sk_buff for example leaves the register typed as
PTR_TO_SOCK_COMMON_OR_NULL, which type_is_sk_pointer() does not match
either, while it actually holds unconverted struct sk_buff bytes. Once
the NULL check has passed this is a type confusion, not just a leak of
kernel data.
Validate src_reg with check_reg_arg() and check the source pointer type
with atomic_ptr_type_ok() before the load again, mirroring
check_atomic_rmw(). Out-of-range register numbers are already rejected
earlier by check_and_resolve_insns() (commit 503d21ef8eac ("bpf: Do
register range validation early")), and the only exemption there,
is_stack_arg_ldx(), requires BPF_LDX | BPF_MEM | BPF_DW and thus never
matches a BPF_ATOMIC insn. atomic_ptr_type_ok() can therefore not
dereference register state out of bounds, that is, the out-of-bounds
read addressed by the Fixes commit below does not reappear (as proven
also via selftest). |
| In the Linux kernel, the following vulnerability has been resolved:
platform/chrome: sensorhub: Fix memory overread in ring handler
`max_response` and `sensor_num` are read from different EC commands:
- `max_response` is from cros_ec_get_proto_info().
ec_dev->max_response = info->max_response_packet_size -
sizeof(struct ec_host_response);
- `sensor_num` is from cros_ec_get_sensor_count().
sensor_num = cros_ec_get_sensor_count(ec);
With a malfunctioning EC firmware, it is possible that the `msg->insize`
(i.e., `fifo_info_length` in the context) could be clamped in
cros_ec_cmd_xfer() because `msg->insize` is greater than `max_response`.
int fifo_info_length =
sizeof(struct ec_response_motion_sense_fifo_info) +
sizeof(u16) * sensorhub->sensor_num;
This means the number of read bytes could be less than expected. As a
result, the subsequent memcpy() in cros_ec_sensorhub_ring_handler()
overreads the `resp->fifo_info` buffer.
Check the return value of cros_ec_cmd_xfer_status() and abort if the
number of bytes read does not match the expected length. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: core: quiesce input in hid_hw_stop() to prevent use-after-free
A driver's probe calls hid_device_io_start() to enable input delivery,
then fails at a later initialization step and unwinds via hid_hw_stop().
The unwind frees struct hidraw via hidraw_disconnect() while in-flight
HID reports may still be running on another CPU, dereferencing the
freed object through hidraw_report_event(). syzbot reports the
resulting use-after-free for the corsair-psu HID driver.
Edward Adam Davis posted a per-driver fix for corsair-psu that adds
an explicit hid_device_io_stop() before hid_hw_stop() in the probe
error path ("hwmon: prevent packets from going to driver for probe",
2026-04-28). Auditing the tree shows 15 drivers call
hid_device_io_start(); 7 also call hid_device_io_stop() and 8 do not:
drivers calling hid_device_io_start() without a matching
hid_device_io_stop() before hid_hw_stop():
drivers/hwmon/corsair-psu.c (fix posted by Edward)
drivers/hwmon/corsair-cpro.c
drivers/hwmon/nzxt-kraken3.c
drivers/hwmon/nzxt-smart2.c
drivers/hwmon/gigabyte_waterforce.c
drivers/hid/hid-logitech-dj.c
drivers/hid/hid-nintendo.c
drivers/hid/hid-mcp2221.c
Roughly half of all callers of the API are exposed. Centralize the
quiesce in hid_hw_stop() so callers do not have to remember the
matching stop: if a driver has left hdev->io_started true on entry,
call hid_device_io_stop() before hid_disconnect().
For the 7 drivers that already call hid_device_io_stop() correctly,
hdev->io_started is false on entry, the guard short-circuits, and
behavior is unchanged.
No Fixes: tag because the affected drivers gained their
hid_device_io_start() calls independently over years; the bug is a
class-wide API misuse rather than a regression from one commit. |
| In the Linux kernel, the following vulnerability has been resolved:
NFSv4.2: fix LAYOUTSTATS send buffer exhaustion
encode_layoutstats_maxsz budgets XDR_QUADLEN(PNFS_LAYOUTSTATS_MAXSIZE),
i.e. 256 bytes, for the layoutupdate4 body written by the layout driver.
The flexfiles record can exceed that.
ff_layout_encode_ff_layoutupdate() emits, per data server, a netaddr4,
an nfs_fh4, two ff_io_latency4, an nfstime4 and a bool. A data server
whose filehandle is NFS_MAXFHSIZE bytes long already accounts for 132 of
those bytes, and the two ff_io_latency4 at 64 bytes each, the nfstime4
and the bool add a further 144, so the body passes 256 bytes before the
netaddr4 is encoded at all. encode_layoutstats() additionally writes
the deviceid4 and the layoutupdate4 lou_type word, neither of which the
macro accounts for.
The filehandle and the address are both chosen by the server, through
LAYOUTGET and GETDEVICEINFO, so it can drive the encoder past the
end of the send buffer. xdr_reserve_space() returns NULL once that
happens, and the two ff_layout_encode_io_latency() calls run with
dss_info->mirror->lock held, so a NULL return there leaves the lock
permanently held.
Raise PNFS_LAYOUTSTATS_MAXSIZE to 384 so that the record fits inside the
reservation. |
| In the Linux kernel, the following vulnerability has been resolved:
net: kcm: Hold RCU read lock while running BPF parser
kcm_parse_func_strparser() calls bpf_prog_run_pin_on_cpu() which
prevents CPU migration, but does not establish an RCU read-side
critical section. Consequently, BPF map operations can trigger
WARN_ON_ONCE(!bpf_rcu_lock_held()) when called from the KCM strparser
program.
Hold the RCU read lock while running the program. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/erdma: Hold CQ references when processing EQ events
EQ handlers look up CQs from dev->cq_xa and invoke CQ completion or
error callbacks outside the xarray lock. erdma_destroy_cq() can erase the
CQ from the xarray and free its queue buffer and doorbell record while a
previously scheduled EQ handler is still using the CQ.
Add a CQ refcount and take a reference under the xarray lock with
refcount_inc_not_zero(). Remove the CQ from the xarray before dropping
the destroy-path reference, then wait for in-flight EQ users before
releasing CQ resources. |
| In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic-v5: Check get_logical_index() return value in MADT IAFFID parsing
In gic_acpi_parse_iaffid() a given MADT GICC entry might not correspond
to a logical cpu recognized by the kernel, resulting in the cpu variable
initialization to an error value.
Currently, the get_logical_index() return value is not checked for failure,
which might result in out-of-bounds memory corruption while trying to
index a per_cpu variable array.
Add a check to evaluate get_logical_index() return value. |

wifi: mt76: mt7921: Add PCIe AER handler support to prevent system crash
When an AER error occurs and the bus is hung, the register reads return

Fix the invalid memory access by validating the DMA index read from the
hardware before it is used as a queue index. An out-of-range value, such
as the 0xFFFFFFFF returned while the bus is hung, is now clamped so it can
no longer corrupt q->head or q->tail. In addition, check the bus_hung flag
in mt7921_mac_reset_work() before attempting the reset sequence, reject MCU
messages while the bus is hung, and install no-op bus operations when an
unrecoverable AER error is detected, preventing further invalid hardware
accesses.
Due to hardware limitations - such as the lack of a connected hardware
reset pin or the absence of host re-probe functionality - affected Wi-Fi
devices may not fully recover to a normal operational state after
certain errors, even with AER enabled. |

| The Ultimate Member WordPress plugin before 2.13.1 does not escape a value derived from user supplied profile names before outputting it in the page title, and decodes HTML entities in it after its own sanitisation has already run, allowing unauthenticated attackers who register an account to store JavaScript that will execute when any visitor, including an administrator, views their profile. |
| In the Linux kernel, the following vulnerability has been resolved:
nfc: llcp: bound SNL TLV parsing to the skb and add length checks
nfc_llcp_recv_snl() walked the SNL TLV list using a u16 offset/length
pair derived from skb->len, without bounding reads to the actual skb
data. Three problems followed:
- For a short frame (skb->len < LLCP_HEADER_SIZE), tlv_len underflowed.
- The per-TLV header (type, length) was read without checking that two
bytes remained.
- A declared TLV length could run past the end of the buffer, and an
SDREQ with length == 0 made "service_name_len = length - 1" underflow
(size_t), driving an out-of-bounds read in the following strncmp() /
nfc_llcp_sock_from_sn(). The SDRES case likewise read tlv[2]/tlv[3]
without a length check.
A nearby NFC device can reach this without authentication; LLCP link
activation happens automatically after NFC-DEP.
Walk the TLV list by pointer, bounded by skb_tail_pointer() over the
linear skb data, and validate each TLV declared length before use. Add
explicit length checks for SDREQ (>= 1) and SDRES (exactly 2).

| In the Linux kernel, the following vulnerability has been resolved:
nvme/ioctl: check SUBMIT_IO with nvme_cmd_allowed()
Unlike IO_CMD / IO64_CMD, NVME_IOCTL_SUBMIT_IO never calls
nvme_cmd_allowed(). Unprivileged callers can thus issue I/O on a
partition device or write through a read-only file descriptor.
Pass flags and open_for_write through and reject disallowed commands
with -EACCES. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_conn: fix the SCO setup context lifetime
hci_setup_sync() queues a conn_handle_t with a NULL destroy callback, so
the context is only freed if hci_enhanced_setup_sync() actually runs. An
entry that is cancelled instead is leaked, as
_hci_cmd_sync_cancel_entry() does not release entry->data when there is
no destroy callback, and hci_cmd_sync_clear() cancels every pending entry
when the controller is unregistered.
The context also stores a bare hci_conn pointer, so the connection can be
freed while the work is queued. The dequeue in hci_conn_del() does not
cover it either, as it matches on entry->data == conn and entry->data is
the wrapper here. Same problem as commit 2f5d635ad590 ("Bluetooth:
hci_sync: hold conn in hci_connect_acl/le_sync() callbacks").
Hold the connection and release both from a destroy callback. The
submission failure path drops both, since hci_cmd_sync_submit() does not
call the destroy callback when it fails to queue. |
| The Asset CleanUp: Page Speed Booster plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content in all versions up to, and including, 1.4.0.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is only exploitable on instances where combine_loaded_css has been enabled. |
