Changes between FreeRTOS V10.4.6 and TBD Changes between FreeRTOS V10.4.6 and FreeRTOS V10.5.0 released September 16 2022

+ ARMv7-M and ARMv8-M MPU ports: It is possible for a third party that
already independently gained the ability to execute injected code to
read from or write to arbitrary addresses by passing a negative argument
as the xIndex parameter to pvTaskGetThreadLocalStoragePointer() or
vTaskSetThreadLocalStoragePointer respectively.
We thank Certibit Consulting, LLC for reporting this issue.
+ ARMv7-M and ARMv8-M MPU ports: It is possible for an unprivileged task to
invoke any function with privilege by passing it as a parameter to
MPU_xTaskCreate, MPU_xTaskCreateStatic, MPU_xTimerCreate,
MPU_xTimerCreateStatic, or MPU_xTimerPendFunctionCall.
We thank Huazhong University of Science and Technology for reporting this issue.
+ ARMv7-M and ARMv8-M MPU ports: It is possible for a third party that has
already independently gained the ability to execute injected code to
achieve further privilege escalation by branching directly inside a
FreeRTOS MPU API wrapper function with a manually crafted stack frame.
We thank Certibit Consulting, LLC, Huazhong University of Science and
Technology and the SecLab team at Northeastern University for reporting
this issue.
+ ARMv7-M MPU ports: It is possible to configure overlapping memory
protection unit (MPU) regions such that an unprivileged task can access
privileged data.
