CVE-2026-102710 · Severity: info · Published 2026-09-29

Eclipse ThreadX is an embedded real-time operating system kernel used in IoT and embedded devices. A user-mode module can register an arbitrary function pointer as a trace callback that executes with kernel privileges when the trace buffer wraps, allowing privilege escalation or denial of service.

## Technical details

A user-mode, memory-protected module can register an arbitrary function pointer as the global trace-full callback via kernel dispatch calls. The kernel invokes this callback directly from privileged code without validation when the trace buffer wraps, allowing execution with kernel privilege. An invalid pointer causes kernel fault (DoS); a valid pointer into module code executes with kernel privilege (nPRIV=0).

## Affected products

- Eclipse ThreadX builds with TX_ENABLE_EVENT_TRACE
