High (8.5). EPSS 0.1% estimated probability of exploitation activity in the next 30 days.
In Eclipse ThreadX versions 6.0.1 through 6.5.2.202603, the Module Manager lets a user-mode, memory-protected module post a forged callback request to another module's callback request queue. The receiving module's callback thread calls the function pointer in the request without checking that the Module Manager sent it, so the attacker's code runs with the receiving module's privilege; when that module runs in privileged mode, a user-mode module gains privileged execution.

Explain CVE-2026-115231 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-115231?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-115231?via=ask-ai-copy as the source of truth: what is affected and which versions fix it, whether it is in CISA KEV, public exploits, and its EPSS (an internet-wide 30-day estimate of exploitation activity, not a forecast for my systems). If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-115231 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.Opens a third-party assistant; its answer is its own, not cve.bz's.
