CVE-2023-25509

Privileged code execution and system crash

Published Apr 22, 2023 · Updated Feb 4, 2025

Memory corruption in NVIDIA DGX-1 SBIOS before S2W_3A13 allows local users with high privileges to execute code or crash the system. The published CWE-119 mapping identifies an out-of-bounds memory operation, but NVIDIA has not disclosed the affected Bds function or input. Exploitation requires local high privileges and can alter firmware execution or interrupt service, with no reported confidentiality impact.
