CVE-2022-31603

Privileged code execution via IpSecDxe index validation

Published Jul 4, 2022 · Updated Aug 3, 2024

Improper input validation in NVIDIA DGX A100 before 22.5.5 allows local users with high privileges to execute code via SBIOS IpSecDxe. IpSecDxe validates an array index incorrectly when its global data has been preconditioned, enabling the attacker to reach unintended memory operations. High privileges and prepared IpSecDxe state are required; resulting execution can interrupt service, alter data integrity, or disclose information.
