CVE-2024-50124

Local unspecified impact via freed ISO socket

Published Nov 5, 2024 · Updated Aug 5, 2026

Use-after-free in Linux kernel Bluetooth ISO sockets allows local users to trigger unspecified impact during socket timeout handling. The iso_sock_timeout path waits for iso_conn_lock after conn->sk can be unlinked and freed, then accesses the stale socket without confirming that it remains in iso_sk_list. Reaching the flaw requires local low-privileged access and a Bluetooth ISO socket race; the published record does not define the resulting effect.
