In short
A flaw in Windows' log file system driver allows someone with user access to gain administrative privileges on the computer. This happens because the driver doesn't properly check the data it receives.
Technical detail
Improper input validation in the Windows Common Log File System Driver (CLFS) permits an authenticated local attacker to achieve privilege escalation through crafted input. The vulnerability requires local access and valid user credentials; successful exploitation grants elevated (administrative) privileges.
