CVE-2026-33827
HighCVSS 8.1Exploitation Probability (EPSS)
Elevated risk54th percentile - higher than 54% of all known CVEs
Summary
A race condition vulnerability in the Windows TCP/IP stack allows an unauthorized attacker to execute code remotely over a network.
Risk Assessment
An attacker can remotely execute code on the target system, potentially leading to full system compromise.
Recommendation
Install the latest Windows security updates from Microsoft.
