Windows CLFS Elevation-of-Privilege Flaws Patched by Microsoft
Microsoft published security advisories for two Windows Common Log File System (CLFS) Driver elevation-of-privilege vulnerabilities, tracked as CVE-2022-37969 and CVE-2023-36424. Both issues affect the CLFS component in Windows and could allow an attacker to gain higher privileges on a targeted system after successful exploitation.
The advisories were released through Microsoft's Security Update Guide and indicate that the flaws were addressed in separate security updates. The repeated appearance of privilege-escalation bugs in the CLFS driver highlights a sensitive Windows kernel-area component that defenders should prioritize for patching and monitoring, especially on endpoints where local code execution could be chained into SYSTEM-level access.
