CVE-2026-77234

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...

CVE-2026-77237

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...

CVE-2026-77237

FreeRTOS-Kernel before version 11.3.1 contains a missing queue-set type validation in the xQueueAddToSet() function. On MPU-enabled ports with configUSE_QUEUE_SETS=1 , an unprivileged task can exploit this to read privileged kernel memory , crossing the memory protection boundary. The CVSS 3.1 sc...

CVE-2026-77234 Improper input validation in FreeRTOS-Kernel timer command handling

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...

CVE-2026-77234

FreeRTOS-Kernel before 11.3.1 contains an improper input validation flaw in timer command handling that allows an unprivileged task on MPU-enabled ports to execute code in privileged kernel context. This represents a privilege escalation from user-space to kernel-space, with high impact on confid...

CVE-2026-72326

CVE-2026-72326 affects the Linux kernel’s net/sched cake scheduler. CAKE accepts signed overhead values stored in an s16, but the adjusted packet length calculation uses unsigned arithmetic, allowing a negative effective length to wrap to a large value. This can cause rate accounting to depend on...

CVE-2026-10669

On Xtensa SoCs built with CONFIGXTENSAMPU and CONFIGUSERSPACE, archbuffervalidate in arch/xtensa/core/mpu.c — the architecture hook that verifies a user-mode-supplied buffer is accessible to the calling user thread with the requested permission — defaulted its return value to 0 access permitted a...

CVE-2021-43997

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...

CVE-2024-28115

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 affe...
