CVE-2026-115654
User-mode module can suspend, terminate, re-prioritise and abort the waits of threads it does not own
In Eclipse ThreadX versions 6.0.1 through 6.5.2.202603, the Module Manager's thread-control services do not check that a thread passed by a user-mode, memory-protected module belongs to that module. Any loaded module can suspend, resume, terminate, reset or re-prioritise application threads and other modules' threads and abort their waits, denying service or changing how the system schedules them.
