Description
Hardware logic with insecure de-synchronization in Intel(R) DSA and Intel(R) IAA for some Intel(R) 4th or 5th generation Xeon(R) processors may allow an authorized user to potentially enable escalation of privilege local access

CAPEC-233MetaDraft
Privilege Escalation
An adversary exploits a weakness enabling them to elevate their privilege and perform an action that they are not supposed to be authorized to perform.

CAPEC-663StandardStable
Exploitation of Transient Instruction Execution
An adversary exploits a hardware design flaw in a CPU implementation of transient instruction execution to expose sensitive data and bypass/subvert access control over restricted resources. Typically, the adversary conducts a covert channel attack to target non-discarded microarchitectural changes caused by transient executions such as speculative execution, branch prediction, instruction pipelining, and/or out-of-order execution. The transient execution results in a series of instructions (gadgets) which construct covert channel and access/transfer the secret data.
