CVE-2026-90256

This is a Use-After-Free (UAF) vulnerability in the Linux kernel's Bluetooth L2CAP subsystem. The hci_conn::l2cap_data field is accessed without adequate locking in l2cap_disconn_ind, reached via the path hci_conn_timeout → hci_proto_disconn_ind → l2cap_disconn_ind. If the l2cap_conn is deleted c...
