Code execution via cuobjdump integer overflow
Published Mar 29, 2022 · Updated Aug 3, 2024
Integer overflow in NVIDIA CUDA Toolkit before 11.6 Update 2 allows remote attackers to execute code through a malformed binary. The cuobjdump utility performs overflow-prone integer processing while parsing the binary, but NVIDIA has not disclosed the affected calculation. Exploitation requires a local user to download the file and run cuobjdump against it, after which attacker-controlled code executes in that user’s context.

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.
