CVE-2026-55716 · Infrastructure
NO FIX YET
A out-of-bounds read in the UEFI firmware routine CheckUefiVgaMode on Intel Server Board D50DNP and M50FCP can expose data from firmware memory. An attacker with privileged local access and a high-complexity setup could read sensitive data.

Only Intel Server Board D50DNP and M50FCP systems running the affected UEFI firmware are in scope. Exploitation needs local privileged access, startup or SMM code, and high-complexity conditions, so the risk is limited on well-administered servers. The sources do not list fixed firmware versions.

Out-of-bounds read in the CheckUefiVgaMode for the Intel(R) Server Board D50DNP and Intel(R) Server Board M50FCP within Ring 0 UEFI may allow an information disclosure. Startup code and smm 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 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.
