Descriptions

FreeRTOS is a real-time operating system for microcontrollers. FreeRTOS Kernel versions through 10.6.1 do not sufficiently protect against local privilege escalation via Return Oriented Programming techniques should a vulnerability exist that allows code injection and execution. These issues affect ARMv7-M MPU ports, and ARMv8-M ports with Memory Protected Unit (MPU) support enabled (i.e. `configENABLE_MPU` set to 1). These issues are fixed in version 10.6.2 with a new MPU wrapper.

FreeRTOS es un sistema operativo en tiempo real para microcontroladores. Las versiones del kernel de FreeRTOS hasta la 10.6.1 no protegen suficientemente contra la escalada de privilegios locales a través de técnicas de programación orientada al retorno en caso de que exista una vulnerabilidad que permita la inyección y ejecución de código. Estos problemas afectan a los puertos MPU ARMv7-M y a los puertos ARMv8-M con soporte de unidad protegida de memoria (MPU) habilitado (es decir, `configENABLE_MPU` establecido en 1). Estos problemas se solucionan en la versión 10.6.2 con un nuevo contenedor MPU.
