CVE-2026-45836

The CVE-2026-45836 entry concerns the Linux kernel Bluetooth L2CAP code. It fixes a null pointer dereference in l2cap_sock_get_sndtimeo_cb by adding the same NULL guard already present in l2cap_sock_resume_cb() and l2cap_sock_ready_cb(). The vulnerability stems from a NULL dereference path in l2c...
