CVE-2022-25334

Secure-supervisor code execution via signature-size overflow

Published Oct 19, 2023 · Updated Aug 3, 2024

Stack-based buffer overflow in Texas Instruments OMAP L138 secure variants allows local users to execute code in secure supervisor context. The mask-ROM SK_LOAD routine trusts the signature-size field of an encrypted module, overflowing the stack and overwriting a SHA256 function pointer. Exploitation requires a forged module and the CEK obtained through CVE-2022-25332; resulting code controls the trusted execution environment.
