In short
A flaw in Windows' logging system driver allows a user with basic access to gain higher privileges and take full control of the computer. This is dangerous because it lets attackers bypass security restrictions.
Technical detail
A buffer overflow vulnerability in the Common Log File System (CLFS) driver enables local privilege escalation through crafted I/O control requests. An authenticated attacker can trigger memory corruption to execute code with kernel privileges, bypassing normal access controls.
