Local privilege escalation
Published Aug 11, 2026 · Updated Aug 11, 2026
Improper access control in Intel Processors allows local users to escalate privileges through Ring 3 user applications. Intel has not disclosed which processor control or operation improperly handles untrusted input. Exploitation requires an authenticated user acting as a simple hardware adversary, high complexity, special internal knowledge, and additional attack requirements; it exposes confidentiality and integrity without interrupting service.
