Routine

HIGH 8.2MITIGATE

CVE-2022-25333 is a high-severity flaw (CVSS 8.2) affecting omap l138 firmware. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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
