CVE-2025-20027
Improper input validation in the UEFI WheaERST module for some Intel(R) reference platforms may allow an escalation of privilege.
Overview
CVE-2025-20027 is a known-severity vulnerability. It was published on March 10, 2026.
Technical description
Improper input validation in the UEFI WheaERST module for some Intel(R) reference platforms 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 present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
