In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: Fix use-after-free bugs caused by scosocktimeout

When the sco connection is established and then, the sco socket is releasing, timeoutwork will be scheduled to judge whether the sco disconnection is timeout. The sock will be deallocated later, but it is dereferenced again in scosock_timeout. As a result, the use-after-free bugs will happen. The root cause is shown below:

Cleanup Thread               |      Worker Thread

scosockrelease | scosockclose | _scosockclose | scosocksettimer | scheduledelayedwork | scosockkill | (wait a time) sockput(sk) //FREE | scosocktimeout | sockhold(sk) //USE

The KASAN report triggered by POC is shown below:
