CVE-2024-28115: Amazon Freertos

High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days.

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

• Amazon Freertos: before 10.6.2 (fixed in 10.6.2)
