CVE-2026-115231: Eclipse ThreadX Module Manager privilege escalation via forged callback

CVE-2026-115231 · Severity: info · Published 2026-11-03

Eclipse ThreadX is a real-time operating system kernel used in embedded devices. A user-mode module can forge callback requests to another module's queue, causing that module's callback thread to execute attacker-controlled code with the target module's privileges. On devices where a privileged module is present, this allows a user-mode attacker to gain kernel-level execution, completely defeating the isolation provided by ThreadX's Module Manager.

Technical details

A memory-protected user-mode module can post forged callback requests to another module's callback queue by walking the kernel queue list and sending messages to queues outside its own memory. The receiving module's callback worker thread calls function pointers from these messages without verifying they originated from the Module Manager, allowing arbitrary code execution in the target module's context. When the receiving module runs in privileged mode, this becomes a privilege escalation to kernel-level access.
