CVE-2025-20105
Improper input validation in some UEFI firmware SMM module for the Intel(R) reference platforms may allow an escalation of privilege.
Published Mar 10, 2026 · updated Jun 17, 2026
Improper input validation in some UEFI firmware SMM module for the Intel(R) reference platforms may allow an escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable local code execution. 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 (high), integrity (high) and availability (high) impacts.
