CVE-2022-26942

Secure supervisor code execution via unchecked pointers

Published Oct 19, 2023 · Updated Aug 3, 2024

Untrusted pointer dereference in Motorola MTM5000 Series Firmware allows local users to execute code in the secure TEE supervisor. The KVL key-management and TETRA cryptographic modules dereference arguments passed from the non-secure supervisor without validating their pointers. Exploitation requires non-secure supervisor-level code execution and exposes the device key, TETRA keys, and confidential cryptographic primitives.
