CVE-2026-41515
Description
A flaw was found in OP-TEE, a Trusted Execution Environment (TEE) for Arm Cortex-A cores. The RSA-OAEP decryption implementation in the NXP CAAM crypto driver uses non-constant-time memory comparison for label hash verification, leading to multiple distinguishable error paths. This vulnerability creates a Manger-style padding oracle, which allows a local attacker to recover RSA-OAEP plaintext by performing approximately 1000-2000 adaptive chosen ciphertext queries.
