Microsoft CLFS.sys Denial of Service
CVE-2024-6768 is a vulnerability in the Common Log File System (CLFS.sys) driver of Windows, caused by improper validation of specified quantities in input data. This flaw leads to an unrecoverable inconsistency, triggering the KeBugCheckEx function and resulting in a Blue Screen of Death (BSoD). The issue affects all versions of Windows 10 and Windows 11, Windows Server 2016, Server 2019 and Server 2022 despite having all updates applied. This Proof of Concept (PoC) shows that by crafting specific values within a .BLF file, an unprivileged user can induce a system crash.
