Service interruption via shared-memory mapping integer overflow
Published Jun 22, 2021 · Updated Aug 4, 2024
Integer overflow in Trusty TLK on NVIDIA Jetson TX1 before 32.5.1 allows local users to interrupt service through shared-memory mapping input. The tz_map_shared_mem function permits an overflowing integer calculation to bypass its boundary checks while processing a shared-memory mapping request. Exploitation requires low local privileges, user interaction, TLK use, and a high-complexity trigger; the documented consequence is limited to 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.
