CVE-2024-23980

Local privilege escalation via buffer-bound failure

Published May 16, 2024 · Updated Aug 20, 2024

Improper buffer restrictions in Intel Server firmware allow privileged local users to escalate privileges through PlatformPfrDxe. Intel names the PlatformPfrDxe UEFI driver but does not disclose the triggering input or precise out-of-bounds operation. Exploitation requires high privileges and local access; Intel's advisory names D50FCP rather than the cataloged D50TNP2MHSVAC system, leaving that applicability unresolved.
