Vulnerability details
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to a race condition in the mac802154 interface removal logic when handling asynchronous transmit completion during interface teardown. A local user can trigger interface removal while transmit completion paths access the interface list to cause a denial of service.
The issue arises because queue wake, stop, and disable paths walk local->interfaces under RCU while bulk hardware teardown removes interface entries.
Affected software
Linux kernel
