CyberRota Analysis
AI-GeneratedThe OP-TEE implementation in Linux versions 3.0.0 to 4.10.0 is vulnerable to 32-bit integer overflows in its AES-GCM authentication tag computation, which can lead to incorrect tag generation when processing payloads exceeding 512 megabytes. This flaw may compromise the integrity of encrypted data, making it a concern for systems relying on OP-TEE for secure operations. Organizations using affected versions should prioritize upgrading to version 4.11.0 or later to mitigate potential security risks.

Original NVD Description
OP-TEE is a Trusted Execution Environment (TEE) designed as companion to a non-secure Linux kernel running on Arm; Cortex-A cores using the TrustZone technology. Starting in version 3.0.0 and prior to version 4.11.0, 32-bit integer overflows in OP-TEE core's AES-GCM implementation cause the authentication tag to be computed with incorrect bit-length values after processing more than 512 megabytes of payload or Additional Authenticated Data (AAD). Version 4.11.0 contains a patch. No known workarounds are available.
