CVE-2022-28200

Privileged code execution via BiosCfgTool bounds violation

Published Jul 2, 2022 · Updated Aug 3, 2024

Out-of-bounds access in NVIDIA DGX A100 firmware before 22.5.5 allows local users with elevated privileges to execute code through BiosCfgTool. BiosCfgTool reads from and writes to addresses beyond the intended SMRAM bounds while processing SBIOS configuration operations. Elevated local privileges are required, and exploitation can cross component boundaries to disclose information, corrupt protected firmware state, interrupt service, or escalate privileges.
