CVE-2022-25333: Flawed SK_LOAD module authenticity check in Texas Instruments OMAP L138

• Severity: high (CVSS 8.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.1% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2023-10-19 · updated 2026-06-17
• Weakness: CWE-347

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.
