CVE-2025-22850

State: Published
Severity: 5.6 Medium
Published: Mar 10, 2026
Updated: Mar 11, 2026
Reserved: Jan 9, 2025

Description

Time-of-check time-of-use race condition in the UEFI PdaSmm module for some Intel(R) reference platforms may allow an information disclosure. System software adversary with a privileged user combined with a high complexity attack may enable data exposure. 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 may impact the confidentiality (high), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
