Only servers built on Intel Server Board D50DNP or M50FCP running UEFI before R01.02.0006. The attacker needs local privileged access and a high-complexity attack, so exposure matters mostly on shared or multi-tenant hosts or where an admin account could be compromised. Everyone else can skip it.

Out-of-bounds write in the XmlCliCommonDxe for the Intel(R) Server Board D50DNP and Intel(R) Server Board M50FCP within Ring 0 UEFI may allow an escalation of privilege. System software adversary with a privileged user combined with a high 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.
