CVE-2026-20713 is a medium-severity flaw (CVSS 4.5) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
Always-incorrect control flow implementation in some firmware for some Intel(R) Xeon(R) processors may allow an escalation of privilege. System software adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability
