Starting in version 4.5.0 and prior to version 4.11.0, the RSA-OAEP decryption implementation in the Hisilicon HPRE crypto driver uses non-constant-time `memcmp()` for label hash verification and has multiple distinguishable error paths. This creates a Manger-style padding oracle that allows an attacker to recover RSA-OAEP plaintext with approximately 1000-2000 adaptive chosen ciphertext queries. Only affects plat-d06 with `CFG_HISILICON_ACC_V3=y`, which seems to be disabled by default. Version 4.11.0 contains a patch. As a workaround, disable Hisilicon HPRE RSA driver with `CFG_HISILICON_ACC_V3=n`."}, {"lang": "es", "value": "OP-TEE es un Entorno de Ejecuci\u00f3n Confiable (TEE) dise\u00f1ado como compa\u00f1ero de un kernel de Linux no seguro ejecut\u00e1ndose en n\u00facleos Arm; Cortex-A usando la tecnolog\u00eda TrustZone.
