Descriptions

The high level operating systems (HLOS) was not providing sufficient memory address information to ensure that secure applications inside Qualcomm Secure Execution Environment (QSEE) only write to legitimate memory ranges related to the QSEE secure application's HLOS client. When secure applications inside Qualcomm Secure Execution Environment (QSEE) receive memory addresses from a high level operating system (HLOS) such as Linux Android, those address have previously been verified as belonging to HLOS memory space rather than QSEE memory space, but they were not verified to be from HLOS user space rather than kernel space. This lack of verification could lead to privilege escalation within the HLOS.

Los sistemas operativos de alto nivel (HLOS) no proveían suficiente información de direcciones de memoria como para garantizar que las aplicaciones seguras dentro de Qualcomm Secure Execution Environment (QSEE) solo escriben en rangos legítimos de memoria relacionados con el cliente de HLOS de la aplicación segura de QSEE. Cuando aplicaciones seguras dentro de Qualcomm Secure Execution Environment (QSEE) reciben direcciones de memoria desde un sistema operativo de alto nivel (HLOS) como Linux Android, estas direcciones han sido verificadas previamente como pertenecientes al espacio de memoria de HLOS en lugar de espacio de memoria de QSEE, pero no se verificó que fueran del espacio de usuario de HLOS en lugar de espacio del kernel. Esta falta de verificación podría conducir a escalada de privilegios dentro del HLOS.
