# CVE-2024-38063: Windows TCP/IP Remote Code Execution Vulnerability

**Signal:** High exploit likelihood. EPSS ranks it in the top 5% of all CVEs for likely exploitation in the next 30 days. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 70.6% , percentile 99: FIRST’s model estimates a 70.6% chance of exploitation activity in the next 30 days, higher than 99% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Editorial verdict: Patch this week. Windows TCP/IP IPv6 Remote Code Execution (CVE-2024-38063) — Serious on paper and worth patching promptly, but there is no known in-the-wild exploitation, public code is a flaky crash-oriented proof of concept, and any machine on August 2024 or later cumulative updates is already fixed.
