CVE-2022-26074

Denial of service via incomplete firmware cleanup

Published Aug 18, 2022 · Updated May 5, 2025

Incomplete cleanup in Intel Server Platform Services firmware allows local users to cause a service interruption on affected systems. Intel identifies only an unspecified firmware subsystem and does not disclose the resource left uncleared or the operation that triggers exhaustion. Exploitation requires privileged local access; denial of service is documented, but whether it causes a hang, crash, or reboot is undisclosed.
