What is CVE-2026-115231 in Eclipse ThreadX?
CVE-2026-115231 is a critical security vulnerability affecting the Module Manager in Eclipse ThreadX escalada de privilegios local, carrying a CVSS score of 8.5. This issue compromises memory protection boundaries between individual software modules.
The official details have been documented and tracked via resources like Referencia técnica en github.com and. Understanding how module queues operate is crucial for developers relying on real-time operating systems.
Who is affected by this vulnerability?
The vulnerability affects Eclipse ThreadX versions 6.0.1 through 6.5.2.202603. Specifically, the Module Manager allows a user-mode, memory-protected module to post a forged callback request directly into another module's callback request queue.
Because the receiving module's callback thread executes the function pointer without validating that the Module Manager actually sent it, an attacker's code runs with the receiving module's privileges vulnerabilidad crítica con CVSS 8.4. When that module operates in privileged mode, the user-mode module successfully gains unauthorized privileged execution.
How do I protect my system?
Mitigating memory corruption flaws in embedded systems requires a rigorous approach to input validation and boundary enforcement between isolated execution contexts.
You can protect your systems by following these hardening steps:
- Audit all custom module implementations and callback request queues.
- Check official security bulletins provided on GitHub security advisory.
- Apply the latest patches or updates released by the maintainers.
- Restrict user-mode modules from interacting with privileged queues.
