| In the Linux kernel, the following vulnerability has been resolved:
spi: spi-qpic-snand: write the feature value before executing SET_FEATURE
qcom_spi_send_cmdaddr() programs NAND_FLASH_CMD/NAND_EXEC_CMD and submits
the descriptors, which makes the controller execute the command
immediately. For SPINAND_SET_FEATURE the value to be written is only
placed into NAND_FLASH_FEATURES afterwards, by qcom_spi_io_op(), in a
second submission - so the chip is programmed with whatever that register
happened to hold from a previous operation, and the intended value is only
applied by the *next* SET_FEATURE.
Measured on a TP-Link Archer AX55 v1 (IPQ5018, ESMT F50L1G41LB): writing
0x40 to the configuration register (0xb0) leaves the chip at 0x00, and the
subsequent write of 0x00 leaves it at 0x40 - every write lands one
operation late.
This stayed unnoticed until v6.18 added SPI-NAND OTP support together
with OTP entries for ESMT chips. spinand_otp_rw() enables OTP mode,
reads, and disables it again, and mtd_otp_nvmem_add() does this during
MTD registration. With the off-by-one, the "disable" write actually
applies the previously requested value, so CFG_OTP_ENABLE ends up set:
the chip stays in OTP mode, every subsequent array read returns the OTP
area instead of the array (UBI reports an empty device) and all writes
fail with -EIO because the OTP area is write protected. On this board
that makes the whole flash unusable and the device unbootable.
Write the feature value into NAND_FLASH_FEATURES as part of the same
transaction, before NAND_EXEC_CMD. While at it, copy only the bytes the
operation actually carries - the previous code dereferenced a 4-byte
pointer on a one-byte buffer (spinand->scratchbuf).
With this patch the flash contents read back bit-identical to a
known-good dump of the same board taken under the vendor firmware
(md5-verified across partitions), and writes work. |
| The Stripe Payment Forms by WP Full Pay WordPress plugin before 8.5.5 does not verify that a subscription belongs to the customer bound to the requesting customer-portal session before cancelling it, allowing a user with a confirmed portal session to cancel subscriptions belonging to other customers.
Exploitation requires the attacker to know the target subscription's identifier, which is high-entropy and not enumerable through the Stripe Payment Forms by WP Full Pay WordPress plugin before 8.5.5. |
| The WP Ultimate CSV Importer WordPress plugin before 9.0 does not properly sanitise and escape imported field values before using them in a SQL statement, which could allow high privilege users such as admin to perform SQL injection attacks. |
| The MasterStudy LMS WordPress Plugin WordPress plugin before 3.7.40 does not verify the amount, receiver, currency or status of a payment notification before marking the corresponding order completed, allowing unauthenticated users to complete full-price orders and gain access to paid content by paying only a token amount. |
| The MasterStudy LMS WordPress Plugin WordPress plugin before 3.7.42 does not correctly restrict access to order information, allowing any user with the instructor role to read other users' order billing details, including name, email address, phone number and postal address, by enumerating order IDs. |
| The Frontend Admin by DynamiApps WordPress plugin before 3.29.11 does not perform a capability check on one of its AJAX actions, allowing any authenticated user, such as a subscriber, to delete arbitrary membership plans. |
| In the Linux kernel, the following vulnerability has been resolved:
net: gro: properly validate BIG TCP aggregation criteria
When GRO attempts to aggregate packets beyond GRO_LEGACY_MAX_SIZE (64KB),
BIG TCP should only be permitted for plain IPv4 TCP and plain IPv6 TCP
(with sufficient MAC header room to insert the temporary HBH jumbo header).
However, commit b1a78b9b9886 ("net: add support for ipv4 big tcp")
loosened the check in skb_gro_receive(), leading to several issues:
1. skb_gro_receive() checked skb_headroom(p) instead of the actual space
before the MAC header (p->mac_header). Because skb_headroom(p) includes
mac_len, crafted frames (e.g. injected via AF_PACKET) can pass the check
with p->mac_header < 8 bytes. When ipv6_gro_complete() inserts the
temporary HBH jumbo header, the memmove() starts before skb->head,
causing an out-of-bounds write and wrapping skb->mac_header.
2. It allowed non-IP protocols such as software VLAN (ETH_P_8021Q /
ETH_P_8021AD) to aggregate beyond 64KB because
p->protocol != ETH_P_IPV6 was true.
3. It checked p->encapsulation instead of NAPI_GRO_CB(skb)->encap_mark,
allowing encapsulated flows (e.g. SIT / IPv6-in-IPv4) to aggregate
beyond 64KB.
Fix skb_gro_receive() to strictly enforce:
- NAPI_GRO_CB(skb)->proto == IPPROTO_TCP
- Not encapsulated (!NAPI_GRO_CB(skb)->encap_mark && !p->encapsulation)
- Protocol must be either ETH_P_IP or ETH_P_IPV6
- If ETH_P_IPV6, p->mac_header must be at least
sizeof(struct hop_jumbo_hdr)
Returning -E2BIG from skb_gro_receive() ensures that packets which cannot
become BIG TCP are cleanly flushed at <= 64KB and delivered intact without
dropping.
This issue does not exist in mainline (7.0+) because the subsystem was
rewritten in commit 81be30c1f5f2 ("net/ipv6: Drop HBH for BIG TCP on RX
side"), making this fix relevant only for older stable branches like
6.18.y. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: synproxy: fix unaligned memory access in timestamp adjustment
Use get_unaligned_be32() and put_unaligned_be32() to safely read and
write the timestamp fields. This prevents performance degradation due to
unaligned memory access or even a crash on strict alignment
architectures.
This follows the implementation of timestamp parsing in the networking
stack at tcp_parse_options() and synproxy_parse_options(). |
| In the Linux kernel, the following vulnerability has been resolved:
ipv6: guard against possible NULL deref in __in6_dev_stats_get()
dev_get_by_index_rcu() could return NULL if the original physical
device is unregistered.

| 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:
libbpf: Reject non-exclusive metadata maps in the signed loader
The loader verifies map->sha against the metadata hash in its
instructions. map->sha is calculated when BPF_OBJ_GET_INFO_BY_FD is
called on the frozen map.
While the map is frozen, the /signed loader/ must also ensure the map
is exclusive, as, without exclusivity (which a hostile host could just
omit when loading the loader), another BPF program with map access can
mutate the contents afterwards, so the check passes on stale data.
With the extra check as part of the signed loader, it now refuses to
move on with map->sha validation if the host set it up wrongly. |
| In the Linux kernel, the following vulnerability has been resolved:
i2c: amd-mp2: Unregister callback on adapter add failure
amd_mp2_register_cb() stores the platform I2C context in the MP2 PCI
driver's callback table before the adapter is registered. If
i2c_add_adapter() fails, probe returns and devres frees the context,
but the PCI driver can still dereference the stale pointer from its IRQ
and system-sleep callbacks.
Unregister the callback before returning the adapter registration error. |

KVM: s390: pci: Fix NULL dereference on AIBV allocation failure
The airq_iv_create() can return NULL on failure, but the return value was
never checked. If it fails, zdev->aibv will be NULL and fail when
dereferenced in kvm_zpci_set_airq(). Add a NULL check and free the
previously allocated AISB bit and zdev->aisb on failure. |
| In the Linux kernel, the following vulnerability has been resolved:
s390/zcrypt: Fix wrong domain value verification with EP11 CPRBs
There is a wrong upper limit check for the domain value when an EP11
CPRB is processed for sending to a crypto card. This check is only
active on custom device nodes but may lead to access heap memory
behind perms->adm when an administrative CPRB is sent.
Add correct limit (AP_DOMAINS = 256) checking to fix this. |
| In the Linux kernel, the following vulnerability has been resolved:
ipvs: do not propagate one-packet flag to synced conns
Synced connections can be created before their destination exists. When
the destination is later added, ip_vs_bind_dest() copies connection flags
from the destination into cp->flags.
IP_VS_CONN_F_ONE_PACKET connections are not synced. If a synced
connection inherits IP_VS_CONN_F_ONE_PACKET while it is already hashed,
expiry can treat it as a one-packet connection and skip unlinking the
existing conn_tab node, leaving stale hash nodes pointing at a freed
struct ip_vs_conn.
Drop IP_VS_CONN_F_ONE_PACKET from destination flags when binding synced
connections. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: ISO: ensure no dangling hcon references in iso_conn
After iso_conn_del(), ISO sockets should not dereference the hcon any
more. Currently, clearing iso_conn::hcon relies on iso_conn_del()
releasing the last reference to the iso_conn.
Simplify this by explicitly clearing conn->hcon in iso_conn_del(), to
avoid more complex reasoning on races about who holds the last
reference. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: validate individual TWT params before driver setup
ieee80211_process_rx_twt_action() only partially validates a received
S1G TWT setup frame before queueing it.
An individual agreement can therefore reach ieee80211_s1g_rx_twt_setup()
with twt->length too short for the full struct ieee80211_twt_params.
The individual path passes twt to drv_add_twt_setup(). Both the tracepoint
and the driver callback consume the complete parameters block, not merely
req_type. Do not pass a short individual agreement to the driver.
Broadcast agreements remain unchanged because they are rejected locally
after accessing only req_type.
[edit commit message to not overclaim lack of validation nor
understate driver impact] |
| In the Linux kernel, the following vulnerability has been resolved:
of: reserved_mem: prevent OOB when too many dynamic regions are defined
On boot, fdt_scan_reserved_mem() saves each dynamically-placed
/reserved-memory subnode into a local array of size
MAX_RESERVED_REGIONS.
If the device tree defines more than MAX_RESERVED_REGIONS
dynamically-placed regions, fdt_scan_reserved_mem() writes past the
end of the local array.
Add a bounds check that logs an error and skips the excess regions,
restoring the original behavior. |
