CVE-2024-36432

Arbitrary memory write via improper input validation

Published Jul 15, 2024 · Updated Aug 2, 2024

Improper input validation in Supermicro X11DPG-series BIOS before 4.4 allows local users to write arbitrary memory. Supermicro has not disclosed the affected BIOS component, accepted input, or validation error that makes the write possible. The published assessment requires local access, high privileges, and high complexity; successful exploitation compromises confidentiality, integrity, and availability beyond the BIOS security boundary.
