CVE-2026-80683

CVE-2026-80683 is a use-after-free vulnerability in the Linux kernel's Bluetooth SCO subsystem . The root cause is a reference-counting bug: the SCO socket stores a sco_conn pointer without holding its own reference. When a socket close() races the Bluetooth controller's Disconnection Complete ev...
