CVE-2022-29510

Local privilege escalation via improper buffer restrictions

Published Nov 14, 2023 · Updated Aug 3, 2024

Improper buffer restrictions in Intel Server Board M10JNP2SB BIOS firmware before 7.219 allow privileged local users to escalate privileges. Intel has not disclosed the affected BIOS component, the input reaching it, or the incorrect buffer operation performed. Exploitation requires high privileges, local access, and high complexity, and successful exploitation crosses a security boundary.
