CVE-2021-34382

Kernel memory corruption via size integer overflow

Published Jun 30, 2021 · Updated Aug 4, 2024

Integer overflow in NVIDIA Jetson TX1 Trusty TLK before 32.5.1 allows local users to write arbitrary kernel addresses. The tz_map_shared_mem function performs unchecked size arithmetic, causing its request and logging buffers to overflow into arbitrary kernel memory. Exploitation requires low local privileges, user interaction, high attack complexity, and a Jetson TX1 configuration that uses TLK.
