CVE-2026-20901
Description
Improper input validation for some Intel(R) Xeon(R) processors within firmware may allow an escalation of privilege. Startup code and smm adversary with a privileged user combined with a high complexity attack may enable data alteration. 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 (none), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (high) and availability (none) impacts.
