Published: 08/09/2026(UTC)Updated: 24/09/2026(UTC)Translated: 09/09/2026(UTC)NVD NIST

Exploitation Probability (EPSS)

Low risk

0.20%

9th percentile - higher than 9% of all known CVEs

Summary

Concurrent execution using shared resource with improper synchronization ('race condition') in Windows TCP/IP allows an authorized attacker to elevate privileges locally.

Risk Assessment

An attacker could exploit the flaw to corrupt data or execute code with elevated privileges.

Recommendation

Apply Windows security patches.
