Privilege escalation via failed GPU mapping cleanup
Published Aug 8, 2024 · Updated Aug 9, 2024
Improper exception handling in NVIDIA Jetson Linux 32.7.4 and earlier allows local users to execute code, escalate privileges, or crash devices. NvGPU error paths in GPU MMU mapping code fail to clean up after a mapping attempt fails, leaving inconsistent mapping state. Exploitation requires local low-privileged access and can cross a security boundary, with confidentiality and integrity impacts and a bounded device-service interruption.

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.
