Privileged code execution via OFBD out-of-bounds access
Published Apr 22, 2023 · Updated Feb 4, 2025
Out-of-bounds access in NVIDIA DGX-2 OFBD before BMC 1.08.00 allows local users with high privileges to execute code. The OFBD handler accesses memory past a buffer's end when a highly privileged user invokes it with a pre-conditioned heap. Exploitation requires local high privileges and controlled heap state; successful access can also disclose information, alter system state, or interrupt service.

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.
