Descriptions

An out-of-bounds read was addressed with improved bounds checking. This issue is fixed in iOS 13.6 and iPadOS 13.6, tvOS 13.4.8, watchOS 6.2.8. An attacker that has already achieved kernel code execution may be able to bypass kernel memory mitigations.

Se abordó una lectura fuera de límites con una comprobación de límites mejorada. Este problema es corregido en iOS versión 13.6 y iPadOS versión 13.6, tvOS versión 13.4.8, watchOS versión 6.2.8. Un atacante que ya haya alcanzado una ejecución de código del kernel puede omitir las mitigaciones de la memoria del kernel
