CVE-2026-74538Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: lock sk in iso_connect_ind Accessing iso_pi(sk)->conn requires lock_sock, which is not taken in the "ev3" part of iso_connect_ind. It may also be NULL if socket has transitioned away from the LISTEN/CONNECT states before locking. Fix by adding lock/release. Recheck hcon is valid after lock acquire where needed. A flaw was found in the Linux kernel's Bluetooth ISO (Isochronous Stream) subsystem. A missing lock when accessing socket connection information within the `iso_connect_ind` function could lead to a null pointer dereference. This vulnerability could allow a local attacker to cause a system crash, resulting in a Denial of Service (DoS). Red Hat severity: Moderate — CVSS 5.5…
