CVE-2025-21969

CVE-2025-21969 is a Linux kernel vulnerability in the Bluetooth stack (L2CAP). The issue is a slab-use-after-free in l2cap_send_cmd when the hci sync path releases l2cap_conn but a worker still references it. The root cause is a race between the hci receive data work queue and the l2cap_conn life...
