Description

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.

Affected products

• FreeRTOS-Kernel: before 10.6.2 — fixed in 10.6.2

How to fix

Upgrade to a fixed version: FreeRTOS-Kernel 10.6.2. Check the vendor advisory for mitigations.
