CVE-2024-36433

Arbitrary memory write via improper input validation

Published Jul 15, 2024 · Updated Aug 2, 2024

Improper input validation in the BIOS of Supermicro X11DPH-T, X11DPH-Tq, and X11DPH-i before 4.4 allows local users to write arbitrary memory. The vendor identifies the locus only as BIOS input handling, which accepts insufficiently validated input before performing a memory write. The public record does not identify the affected handler or input format; exploitation requires high local privileges and high complexity.
