CVE-2024-28115

Local privilege escalation via MPU-wrapper ROP

Published Mar 7, 2024 · Updated Aug 28, 2024

Improper access control in FreeRTOS Kernel 10.6.1 and earlier allows local users to gain kernel privileges through injected ROP code. The affected MPU wrapper inadequately isolates privileged system-call execution from attacker-controlled return-oriented control flow. Exploitation requires a separate code-injection flaw on an ARMv7-M MPU port or an ARMv8-M port with configENABLE_MPU set to 1.
