Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2023-36424 is an elevation-of-privilege vulnerability in the Windows Common Log File System (CLFS) Driver, stemming from an out-of-bounds read (CWE-125). The flaw affects the kernel-mode driver responsible for handling log files on Windows systems and carries a CVSS 3.1 score of 7.8, reflecting local attack vector, low complexity, and low required privileges.
A local attacker with a low-privileged account can exploit the flaw to read memory beyond intended bounds, enabling escalation to higher privileges and full compromise of confidentiality, integrity, and availability on the affected host.
Microsoft has published updates addressing the issue through its Security Response Center, while CISA includes the CVE in its Known Exploited Vulnerabilities catalog, indicating that federal agencies must apply the patches according to the published timelines.
EPSS for the vulnerability rose from a low baseline to a peak of 0.2029 on 2025-12-11 before receding to the current value of 0.0976, demonstrating a clear post-disclosure increase in exploitation interest that later moderated.
