{"id":"CVE-2026-50249","kind":"vulnerability","aliases":["CVE-2026-50249"],"related":[],"title":"Intel server board UEFI firmware: out-of-bounds read leaks data locally","description":"Out-of-bounds read in the GenerationSetup 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.","summary":"Intel server boards D50DNP and M50FCP have an out-of-bounds read in GenerationSetup inside their Ring 0 UEFI firmware.
