CVE-2023-25521

Privilege escalation via improper SBIOS parameter validation

Published Jul 3, 2023 · Updated Nov 27, 2024

Improper input validation in NVIDIA DGX A100 and A800 SBIOS before 1.21 allows local users to execute code with elevated privileges. NVIDIA has not published the affected input parameter, SBIOS routine, or the operation that mishandles the parameter. Exploitation requires existing high privileges and local access; successful attacks can cause a service interrupt, disclose information, or tamper with data.
