CVE-2026-109588 Numeric truncation in the MPU buffer authorization check in FreeRTOS-Kernel
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 kernel memory beyond th...
CVE-2026-109588
The FreeRTOS-Kernel (versions V11.3.0 and V11.3.1 ) is vulnerable to a numeric truncation error in the MPU buffer authorization check on the Arm Cortex-R82 (Armv8-R AArch64) MPU port. This flaw may allow an unprivileged task on MPU-enabled builds to read or write privileged kernel memory beyond t...

FreeRTOS-FreeRTOS-Kernel Authorization Issues Vulnerability
FreeRTOS’ FreeRTOS-Kernel versions 11.3.0 and 11.3.1 have an authorization-related vulnerability. This vulnerability stems from improper authorization for the Arm Cortex-R8 MPU port. It may allow non-privileged tasks to read from and write to privileged kernel memory outside the allocated area,...
CVE-2026-77237: Access of Resource Using Incompatible Type
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 configUSEQUEUESETS=1 to read privileged kernel memory. To remediate this issue, users should upgrade to version 11.3.1 or later...
