https://notcve.org/view.php?id=CVE-2021-27504
21 Nov 2023 — Texas Instruments devices running FREERTOS, malloc returns a valid pointer to a small buffer on extremely large values, which can trigger an integer overflow vulnerability in 'malloc' for FreeRTOS, resulting in code execution. En los dispositivos de Texas Instruments que ejecutan FREERTOS, malloc devuelve un puntero válido a un pequeño búfer en valores extremadamente grandes, lo que puede desencadenar una vulnerabilidad de desbordamiento de enteros en 'malloc' para FreeRTOS, lo que resulta en la ejecución d... • https://www.cisa.gov/news-events/ics-advisories/icsa-21-119-04 • CWE-190: Integer Overflow or Wraparound •

17 Nov 2021 — FreeRTOS versions 10.2.0 through 10.4.5 do not prevent non-kernel code from calling the xPortRaisePrivilege internal function to raise privilege. FreeRTOS versions through 10.4.6 do not prevent 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. These issues affect ARMv7-M MPU ports, and ARMv8-M ports with MPU support enabled (i.e.... • https://github.com/FreeRTOS/FreeRTOS-Kernel/releases/tag/V10.4.3-LTS-Patch-2 •
