Buffer overflow in Intel(r) Reference Platforms May Allow An Escalation Of Privilege. System Software Adversary With A Privileged User Combined High Complexity Attack Enable Data Manipulation. This Result Potentially Occur Via Local Access When Requirements Are Not Present Without Special Internal Knowledge And Requires No Interaction. The Potential Vulnerability Impact Confidentiality (None), Integrity (High) Availability (Low) Vulnerable System, Resulting In Subsequent (None) Impacts.

CVE-2025-20005

Improper buffer restrictions in some UEFI firmware 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 data manipulation. 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 (none), integrity (high) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
