CVE-2026-71969

OP-TEE OS through 4.10.0, fixed in commit 7b8b494, contains a buffer underwrite vulnerability in the RSA NOPAD encrypt and decrypt operations within the mbedTLS software backend and SE050 hardware driver that allows a malicious Trusted Application to corrupt secure-world heap memory by supplying ...

CVE-2026-71969 OP-TEE OS 4.10.0 Buffer Underwrite via RSA NOPAD Encrypt/Decrypt Operations

OP-TEE OS through 4.10.0, fixed in commit 7b8b494, contains a buffer underwrite vulnerability in the RSA NOPAD encrypt and decrypt operations within the mbedTLS software backend and SE050 hardware driver that allows a malicious Trusted Application to corrupt secure-world heap memory by supplying ...

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...
