CVE-2026-119086

תיאור (מקור, אנגלית)

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, affecting privileged memory across the MPU isolation boundary. To remediate this issue, users should upgrade to FreeRTOS-Kernel V11.3.3, rebuild, and reflash affected firmware. Builds that do not enable queue sets are not affected.
