CVE-2026-94192 Eclipse Foundation CVE debrief

A ThreadX module allocates control blocks of its kernel objects from the Module Manager's object pool and can deallocate them by address using `txm_module_object_deallocate`. However, the manager does not check if the object is still in use by the kernel, leading to potential issues. This can cause system instability or crashes if the deallocated object is still referenced by the kernel. The vulnerability occurs because deallocation does not remove the object from its type's created list, leaving it schedulable if it's a thread or active if it's a timer.

Who should care

Defenders responsible for managing and maintaining ThreadX-based systems should assess exposure and verify versions to prevent potential issues. This includes reviewing system configurations, monitoring system stability, and investigating any anomalies. Operators, platform administrators, and security teams should also be aware of the vulnerability's impact and take necessary precautions to mitigate potential risks.

Why it matters

CVE-2026-94192 allows deallocation of live kernel objects in ThreadX, potentially leading to system instability. Defenders should verify versions, review configurations, and monitor system stability.

  • Verification of Eclipse ThreadX versions is required to determine exposure.
  • System instability or crashes could occur if live kernel objects are deallocated.
  • Defenders should review system configurations and kernel object management to prevent potential issues.

Technical summary

The vulnerability occurs in the `txm_module_object_deallocate` function, which allows deallocation of kernel objects without checking if they are still in use. This could lead to system instability or crashes if the deallocated object is still referenced by the kernel. The issue arises from the deallocation process not removing the object from its type's created list, leaving threads schedulable and timers active. Defenders should prioritize verifying the versions of Eclipse ThreadX in use and assessing exposure, as the vulnerability allows deallocation of live kernel objects.

Defensive priority

Defenders should prioritize verifying the versions of Eclipse ThreadX in use and assessing exposure, as the vulnerability allows deallocation of live kernel objects, which could lead to system instability or crashes.

Recommended defensive actions

  • Verify the version of Eclipse ThreadX in use and assess exposure.
  • Review system configurations and kernel object management to prevent potential issues.
  • Monitor system stability and crashes, and investigate any anomalies.
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review.
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented.
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
  • Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
