What is CVE-2024-12668?
CVE-2024-12668 is a high-severity memory corruption vulnerability in Velocidex WinPmem, published on 16 Dec 2024. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
Velocidex WinPmem versions below 4.1 suffer from an Out of Bounds Write vulnerability. By using an IO Control, a user space program can trick the driver into writing a 0 into any chosen memory location. In conjunction with information leakage from the WinPmem driver, attackers can discover the location in memory for the g_CiOptions global symbol. This can be leveraged to disable signed driver enforcement on the target system - allowing attackers to load unsigned drivers.
Weakness: CWE-787
