CVE-2026-113421

In Eclipse ThreadX versions 6.0.1 through 6.5.2.202603, ThreadX Modules does not revoke a module's trace-buffer-full callback when the module is stopped and unloaded. With event tracing enabled and a kernel-owned trace buffer still active, a later buffer wrap invokes the callback from privileged thread context after the module's code has been released, so a user-mode module can have its code run with kernel privileges after unload, or, once the memory is reused, redirect control flow or cause a fault.

Description from the National Vulnerability Database, published by emo@eclipse.org

What to do: Apply the vendor’s update. The NVD record links to the advisory.

What it means for a small business

If your business uses Eclipse ThreadX, install the vendor's update. If you're not sure whether you use it, ask whoever manages your computers.

How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 0.11%, higher than 1% of CVEs. That’s low, but low isn’t zero, and the odds jump the day someone publishes an exploit. Scored November 3, 2026, updated daily.

Check your own setup

  • Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
  • Server check: what your web server says about itself, and whether that version has known flaws.
