CVE-2026-71969

OP-TEE OS 4.10.0 contains a buffer underwrite in the RSA NOPAD encrypt/decrypt path (mbedTLS backend and SE050 driver). When src_len > rsa_len, the subtraction wraps to a large unsigned value, causing a memcpy to write attacker-controlled data into secure-world heap memory in S-EL1. The vulner...
