Only servers built on Intel Server Board D50DNP or M50FCP with the affected XmlCliCommonDxe firmware are exposed. The attack needs local access and a privileged user, plus a high-complexity condition, so machines reachable only by trusted administrators carry less risk. Teams running other Intel or non-Intel boards can skip it.

Who cares bios, intel, server-firmware, uefi
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. Startup code and smm 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.
