Local integer overflow in shared-memory mapping
Published Jun 30, 2021 · Updated Aug 4, 2024
Integer overflow in NVIDIA Jetson TX1 Jetson Linux before 32.5.1 allows local users to cause denial of service, information disclosure, or data tampering. The Trusty TLK tz_map_shared_mem function fails to check the size parameter before mapping shared memory, allowing an attacker-controlled overflow. Exploitation requires local low-privilege access and user interaction; the published impact is confined to availability, confidentiality, and integrity effects on the device.
