Descriptions
In ARM Trusted Firmware 1.3, RO memory is always executable at AArch64 Secure EL1, allowing attackers to bypass the MT_EXECUTE_NEVER protection mechanism. This issue occurs because of inconsistency in the number of execute-never bits (one bit versus two bits).
En Trusted Firmware versión 1.3 de ARM, la memoria RO es siempre ejecutable en AArch64 Secure EL1, lo que permite a los atacantes eludir el mecanismo de protección MT_EXECUTE_NEVER. Este problema ocurre debido a la inconsistencia en el número de bits de nunca ejecutados (un bit contra dos bits).
