🚨 CVE-2026-9757
The GEO my WP plugin for WordPress is vulnerable to SQL Injection via the 'swlatlng' and 'nelatlng' parameters in all versions up to, and including, 4.5.5 The parameters are read from $_SERVER['QUERY_STRING'] via parse_str() (bypassing WordPress's wp_magic_quotes protection, which only covers $_POST/$_GET/$_COOKIE/$_REQUEST), then each is split on ',' via explode() and the resulting fragments are interpolated directly into a SQL BETWEEN clause in gmw_get_locations_within_boundaries_sql() without is_numeric() validation, (float) casting, esc_sql(), or $wpdb->prepare(). This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation requires the site to host the Posts Locator search-results shortcode (`[gmw form="results" form_id=N]`) on a public page and to have at least one published post with an associated gmw_location row.

🚨 CVE-2026-45192
A bug in the GET `/api/v2/connections/{connection_id}` REST API endpoint in Apache Airflow allowed an authenticated UI/API user with Connection-read permission to retrieve secrets stored in a Connection's `extra` JSON blob under field names not present in the redaction allowlist (`DEFAULT_SENSITIVE_FIELDS`) — for example, official Slack-provider credential field names were returned in plaintext. Affects deployments that store credentials in Connection `extra` blobs and grant Connection-read access to multiple users. Users are advised to upgrade to `apache-airflow` 3.2.2 or later. As a defense-in-depth mitigation, deployment operators can store sensitive credential values in a secret-backend rather than inlined into the Connection's `extra` field.

🚨 CVE-2026-53073
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_ldisc: Clear HCI_UART_PROTO_INIT on error
When hci_register_dev() fails in hci_uart_register_dev()
HCI_UART_PROTO_INIT is not cleared before calling hu->proto->close(hu)
and setting hu->hdev to NULL. This means incoming UART data will reach
the protocol-specific recv handler in hci_uart_tty_receive() after
resources are freed.
Clear HCI_UART_PROTO_INIT with a write lock before calling
hu->proto->close() and setting hu->hdev to NULL. The write lock ensures
all active readers have completed and no new reader can enter the
protocol recv path before resources are freed.
This allows the protocol-specific recv functions to remove the
"HCI_UART_REGISTERED" guard without risking a null pointer dereference
if hci_register_dev() fails.

bpf: Fix OOB in pcpu_init_value
An out-of-bounds read occurs when copying element from a
BPF_MAP_TYPE_CGROUP_STORAGE map to another pcpu map with the
same value_size that is not rounded up to 8 bytes.
The issue happens when:
1. A CGROUP_STORAGE map is created with value_size not aligned to
8 bytes (e.g., 4 bytes)
2. A pcpu map is created with the same value_size (e.g., 4 bytes)
3. Update element in 2 with data in 1
pcpu_init_value assumes that all sources are rounded up to 8 bytes,
and invokes copy_map_value_long to make a data copy, However, the
assumption doesn't stand since there are some cases where the source
may not be rounded up to 8 bytes, e.g., CGROUP_STORAGE, skb->data.
the verifier verifies exactly the size that the source claims, not
the size rounded up to 8 bytes by kernel, an OOB happens when the
source has only 4 bytes while the copy size(4) is rounded up to 8.

🚨 CVE-2026-53078
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix same-register dst/src OOB read and pointer leak in sock_ops
When a BPF sock_ops program accesses ctx fields with dst_reg == src_reg,
the SOCK_OPS_GET_SK() and SOCK_OPS_GET_FIELD() macros fail to zero the
destination register in the !fullsock / !locked_tcp_sock path.
Both macros borrow a temporary register to check is_fullsock /
is_locked_tcp_sock when dst_reg == src_reg, because dst_reg holds the
ctx pointer. When the check is false (e.g., TCP_NEW_SYN_RECV state with
a request_sock), dst_reg should be zeroed but is not, leaving the stale
ctx pointer:
- SOCK_OPS_GET_SK: dst_reg retains the ctx pointer, passes NULL checks
as PTR_TO_SOCKET_OR_NULL, and can be used as a bogus socket pointer,
leading to stack-out-of-bounds access in helpers like
bpf_skc_to_tcp6_sock().
- SOCK_OPS_GET_FIELD: dst_reg retains the ctx pointer which the
verifier believes is a SCALAR_VALUE, leaking a kernel pointer.
Fix both macros by:
- Changing JMP_A(1) to JMP_A(2) in the fullsock path to skip the
added instruction.
- Adding BPF_MOV64_IMM(si->dst_reg, 0) after the temp register
restore in the !fullsock path, placed after the restore because
dst_reg == src_reg means we need src_reg intact to read ctx->temp.

🚨 CVE-2026-53094
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix stale offload->prog pointer after constant blinding
When a dev-bound-only BPF program (BPF_F_XDP_DEV_BOUND_ONLY) undergoes
JIT compilation with constant blinding enabled (bpf_jit_harden >= 2),
bpf_jit_blind_constants() clones the program. The original prog is then
freed in bpf_jit_prog_release_other(), which updates aux->prog to point
to the surviving clone, but fails to update offload->prog.
This leaves offload->prog pointing to the freed original program. When
the network namespace is subsequently destroyed, cleanup_net() triggers
bpf_dev_bound_netdev_unregister(), which iterates ondev->progs and calls
__bpf_prog_offload_destroy(offload->prog). Accessing the freed prog
causes a page fault:
BUG: unable to handle page fault for address: ffffc900085f1038

The test sequence that triggers this reliably is:
1. Set net.core.bpf_jit_harden=2 (echo 2 > /proc/sys/net/core/bpf_jit_harden)
2. Run xdp_metadata selftest, which creates a dev-bound-only XDP
program on a veth inside a netns (./test_progs -t xdp_metadata)
3. cleanup_net -> page fault in __bpf_prog_offload_destroy
Dev-bound-only programs are unique in that they have an offload structure
but go through the normal JIT path instead of bpf_prog_offload_compile().
This means they are subject to constant blinding's prog clone-and-replace,
while also having offload->prog that must stay in sync.
Fix this by updating offload->prog in bpf_jit_prog_release_other(),
alongside the existing aux->prog update. Both are back-pointers to
the prog that must be kept in sync when the prog is replaced.

The DEVMAP_HASH branch in dev_map_redirect_multi() uses
hlist_for_each_entry_safe() to iterate hash buckets, but this function
runs under RCU protection (called from xdp_do_generic_redirect_map()
in softirq context). Concurrent writers (__dev_map_hash_update_elem,
dev_map_hash_delete_elem) modify the list using RCU primitives
(hlist_add_head_rcu, hlist_del_rcu).
hlist_for_each_entry_safe() performs plain pointer dereferences without
rcu_dereference(), missing the acquire barrier needed to pair with
writers' rcu_assign_pointer(). On weakly-ordered architectures (ARM64,
POWER), a reader can observe a partially-constructed node. It also
defeats CONFIG_PROVE_RCU lockdep validation and KCSAN data-race
detection.
Replace with hlist_for_each_entry_rcu() using rcu_read_lock_bh_held()

used in the DEVMAP (non-hash) branch of the same functions. Also fix

bpf: Switch CONFIG_CFI_CLANG to CONFIG_CFI
This was renamed in commit 23ef9d439769 ("kcfi: Rename CONFIG_CFI_CLANG
to CONFIG_CFI") as it is now a compiler-agnostic option. Using the wrong
name results in the code getting compiled out. Meaning the CFI failures
for btf_dtor_kfunc_t would still trigger.

🚨 CVE-2026-53100
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: fix deadlock in remain-on-channel
mt76_remain_on_channel() and mt76_roc_complete() call mt76_set_channel()
while already holding dev->mutex. Since mt76_set_channel() also acquires
dev->mutex, this results in a deadlock.
Use __mt76_set_channel() instead of mt76_set_channel().
Add cancel_delayed_work_sync() for mac_work before acquiring the mutex
in mt76_remain_on_channel() to prevent a secondary deadlock with the
mac_work workqueue.

🚨 CVE-2026-53101
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7921: fix potential deadlock in mt7921_roc_abort_sync
roc_abort_sync() can deadlock with roc_work(). roc_work() holds
dev->mt76.mutex, while cancel_work_sync() waits for roc_work()
to finish. If the caller already owns the same mutex, both
sides block and no progress is possible.
This deadlock can occur during station removal when
mt76_sta_state() -> mt76_sta_remove() -> mt7921_mac_sta_remove() ->
mt7921_roc_abort_sync() invokes cancel_work_sync() while
roc_work() is still running and holding dev->mt76.mutex.
This avoids the mutex deadlock and preserves exactly-once
work ownership.

🚨 CVE-2026-53102
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: Fix memory leak after mt76_connac_mcu_alloc_sta_req()
mt76_connac_mcu_alloc_sta_req() allocates an skb which is expected to
be freed eventually by mt76_mcu_skb_send_msg(). However, currently if
an intermediate function fails before sending, the allocated skb is
leaked.
Specifically, mt76_connac_mcu_sta_wed_update() and
mt76_connac_mcu_sta_key_tlv() may fail, leading to an immediate memory
leak in the error path.
Fix this by explicitly freeing the skb in these error paths.
Commit 7c0f63fe37a5 ("wifi: mt76: mt7996: fix memory leak on
mt7996_mcu_sta_key_tlv error") made a similar change.
Compile tested only. Issue found using a prototype static analysis tool
and code review.
