Name of the Vulnerable Software and Affected Versions Texas Instruments OMAP L138 (secure variants) (affected versions not specified)

Description The trusted execution environment (TEE) lacks a bounds check on the signature size field in the SK LOAD module loading routine, present in mask ROM. A module with a sufficiently large signature field causes a stack overflow, affecting secure kernel data pages. This can be leveraged to obtain arbitrary code execution in secure supervisor context by overwriting a SHA256 function pointer in the secure kernel data area when loading a forged, unsigned SK LOAD module encrypted with the CEK. This constitutes a full break of the TEE security architecture.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
