+	  ensure that passing a negative argument as the xIndex parameter does not
+	  cause arbitrary read or write.

 	  achieve further privilege escalation by branching directly inside a
 	  FreeRTOS MPU API wrapper function with a manually crafted stack frame.
+	  The local stack variable `xRunningPrivileged` has been removed so that
+	  a manually crafted stack frame cannot be used for privilege escalation
+	  by branching directly inside a FreeRTOS MPU API wrapper.

+	+ ARMv7-M MPU ports: It was possible to configure overlapping memory
+	  protection unit (MPU) regions such that an unprivileged task could access
+	  privileged data. The kernel now uses highest numbered MPU regions for

 	+ Add support for ARM Cortex-M55.
 	+ Add support for ARM Cortex-M85. Contributed by @gbrtth.
 	+ Add vectored mode interrupt support to the RISC-V port.
