Missing queue-set type validation in the queue-set selection system call in FreeRTOS-Kernel before V11.3.3 on MPU-enabled ports with queue sets enabled allows a local unprivileged task to write actor-controlled data beyond a pointer-sized object on the privileged kernel stack, af...
Numeric truncation of the buffer length in the MPU buffer authorization check in FreeRTOS-Kernel V11.3.0 and V11.3.1 on the Arm Cortex-R82 (Armv8-R AArch64) MPU port might allow, under certain conditions, an unprivileged task on MPU-enabled builds to read or write privileged kern...
Incorrect authorization in the Arm Cortex-R82 (Armv8-R AArch64) MPU port in FreeRTOS-Kernel V11.3.0 and V11.3.1 might allow an unprivileged task on MPU-enabled builds to read and write privileged kernel memory outside the regions assigned to it, via a buffer argument passed to an...
Missing queue-set type validation in xQueueAddToSet() in the FreeRTOS-Kernel before 11.3.1 might allow an unprivileged task on MPU-enabled ports with configUSE_QUEUE_SETS=1 to read privileged kernel memory. To remediate this issue, users should upgrade to version 11.3.1 or later.
Missing minimum size validation in secure context allocation in FreeRTOS-Kernel before 11.3.1 might allow local users to corrupt secure-world heap metadata via an out-of-bounds write with an undersized stack size parameter. To remediate this issue, users should upgrade to version...
Missing privilege verification in the secure context cleanup handler in FreeRTOS-Kernel before 11.3.1 might allow local users to cause a use-after-free condition in secure-world memory via the SVC handler for secure context deallocation. To remediate this issue, users should upgr...
Improper input validation in FreeRTOS-Kernel before 11.3.1 might allow an unprivileged task on MPU-enabled ports to execute code in privileged kernel context. To remediate this issue, users should upgrade to version 11.3.1 or later.
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....
