Overview
About vulnerability
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.
