Attack conditions (Source advisory, CVSS 3.1): Local · Low privileges required · No user interaction required

What an attacker can do

The source says however, if the driver is forced to unbind while the exec queue is still running, the user may call exec_destroy() after the GuC has already been stopped and CT communication disabled. Source advisory’s CVSS 3.1 assessment (base score 7.8/10) rates confidentiality, integrity and availability impact as high.
