What is CVE-2022-25333?
CVE-2022-25333 is a high-severity vulnerability in Texas Instruments OMAP, published on 19 Oct 2023. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
The Texas Instruments OMAP L138 (secure variants) trusted execution environment (TEE) performs an RSA check implemented in mask ROM when loading a module through the SK_LOAD routine. However, only the module header authenticity is validated. An adversary can re-use any correctly signed header and append a forged payload, to be encrypted using the CEK (obtainable through CVE-2022-25332) in order to obtain arbitrary code execution in secure context. This constitutes a full break of the TEE security architecture.
