CVE-2023-40090

Estado: ModificadaMedia (6.5)—

En BTM_BleVerifySignature de btm_ble.cc, existe una forma posible de omitir la validación de firma debido a la divulgación de información del canal lateral. Esto podría conducir a una escalada remota de privilegios sin necesidad de permisos de ejecución adicionales. La interacción del usuario no es necesaria para la explotación.
