Privileged-user local privilege escalation
Published Feb 17, 2021 · Updated Aug 4, 2024
Improper input validation in Intel Graphics Drivers before 27.20.100.8587 allows local users to gain elevated privileges. Intel has not published the affected function or the invalid input operation that fails validation. Exploitation requires high-privilege local access and high attack complexity, and successful exploitation can modify protected state beyond the original security authority.
