HighCVSS 8.8Exploitation Probability (EPSS)
Low risk15th percentile - higher than 15% of all known CVEs
Summary
An out-of-bounds read vulnerability in the Windows kernel allows an authorized attacker to elevate privileges locally. This flaw can be exploited to gain higher-level access on the affected system.
Risk Assessment
The risk involves privilege escalation by an authenticated user, potentially leading to full system compromise and unauthorized access to sensitive information.
Recommendation
Apply the security update provided by Microsoft for the Windows kernel immediately. Additionally, restrict system access to trusted users only.
