Improper Hardware reset flow logic in the GPU GFX Hardware IP block could allow a privileged attacker in a guest virtual machine to control reset operation potentially causing host or GPU crash or reset resulting in denial of service.
Weakness
Faulty finite state machines (FSMs) in the hardware logic allow an attacker to put the system in an undefined state, to cause a denial of service (DoS) or gain privileges on the victim’s system.
Extended Description
The functionality and security of the system heavily depend on the implementation of FSMs. FSMs can be used to indicate the current security state of the system. Lots of secure data operations and data transfers rely on the state reported by the FSM.
