High-privilege code execution via chained integer overflow
Published Jul 4, 2022 · Updated Aug 3, 2024
Integer overflow in NVIDIA DGX A100 SBIOS before 22.5.5 allows local users to execute code and compromise the system. NVIDIA identifies SmmCore as the locus but has not disclosed the overflowing operation or attacker-controlled input path. Exploitation requires high privileges and another vulnerability in the chain; effects extend beyond SBIOS, while the denial-of-service mode is undisclosed.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
