Denial of service attacks can render the computer or the GPU inoperable, either by forcing a crash or by flooding it with more information than it can handle.
Privilege escalation can work in two ways: it can let attackers imitate other users or network devices to access their information and abilities (horizontal escalation), or it can let them access all data and control the computer (vertical escalation).
Code execution lets attackers run any software they want, and information disclosure means that attackers can see anything from how devices are configured to stored passwords.
