CVE-2026-74538 - Vulnerability Details - OpenCVE

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.

No CVSS v4.0

No CVSS v3.1
