Local privilege escalation via out-of-bounds write
Published Feb 17, 2021 · Updated Aug 4, 2024
An out-of-bounds write in Intel Graphics Driver allows local users to escalate privileges through local access on affected systems. Intel has not published the affected function, buffer, or unchecked value; only the write beyond a buffer boundary is disclosed. Exploitation requires low-privileged local access and user interaction, and successful use can compromise confidentiality and integrity and interrupt service.
