CVE-2026-41514

OP-TEE affects Cortex-A TrustZone, with RSA-OAEP decryption in the Hisilicon HPRE driver vulnerable from v4.5.0 up to v4.11.0 due to non-constant-time memcmp() in label hash verification and multiple distinct error paths. This creates a padding oracle allowing plaintext recovery on ~1,000–2,000 a...
