Overview
CVE-2023-36424 is a Windows Common Log File System Driver Elevation of Privilege Vulnerability that was discovered and disclosed in November 2023. The vulnerability affects various versions of Microsoft Windows operating systems, including Windows 10, Windows 11, and Windows Server editions (NVD, MITRE).
Technical details
The vulnerability has been assigned a CVSS v3.1 base score of 7.8 (HIGH) with the vector string CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H.
