HighCVSS 7.8Exploitation Probability (EPSS)
Low risk15th percentile - higher than 15% of all known CVEs
Summary
Use after free in Windows TCP/IP allows an authorized attacker to elevate privileges locally.
Risk Assessment
An attacker could exploit the flaw to escalate privileges, potentially leading to control over network functions.
Recommendation
Apply security patches for Windows TCP/IP stack from Microsoft.
