CVE-2026-20712: Medium severity vulnerability
Incomplete cleanup in some UEFI firmware for some Intel(R) reference platforms within UEFI may allow an information disclosure. System software adversary with a privileged user combined with a low complexity attack may enable data exposure. 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 (high), integrity (none) and availability (none) impacts.
