Windows Common Log File System Driver Elevation of Privilege Vulnerability
CVE-2025-62470 is a local elevation-of-privilege vulnerability in the Windows Common Log File System (CLFS) Driver. The provided content identifies the flaw as a heap-based buffer overflow in the Windows Common Log File System Driver that allows an authorized attacker to elevate privileges locally. Based on the available information, exploitation occurs in kernel-mode CLFS driver code and results from improper handling of memory on the heap, enabling corruption of adjacent memory structures. Microsoft and third-party reporting describe it as an Important-severity Windows privilege-escalation issue and assess it as more likely to be exploited.
