CVE-2022-36392Network attack vector

Unauthenticated service interruption via improper input validation

Published Aug 11, 2023 · Updated Feb 13, 2025

Improper input validation in Intel Standard Manageability firmware allows remote attackers to interrupt service over a network. Intel has not disclosed the input, processing locus, or invalid operation that triggers the denial of service. The interface is reachable without authentication, and the published impact is limited to availability without distinguishing a hang, crash, or reboot.
