Explain CVE-2026-124914 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-124914?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-124914?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).

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.
