CVE-2024-12668 (GCVE-0-2024-12668)
Vulnerability from cvelistv5 – Published: 2024-12-16 14:56 – Updated: 2024-12-16 16:14
VLAI?
Summary
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.
Severity ?
8.2 (High)

CVE-2024-10972 (GCVE-0-2024-10972)
Vulnerability from cvelistv5 – Published: 2024-12-16 14:49 – Updated: 2025-09-05 08:40
VLAI?
Summary
Velocidex WinPmem versions 4.1 and below suffer from an Improper Input Validation vulnerability whereby an attacker with admin access can trigger a BSOD with a parallel thread changing the memory’s access right under the control of the user-mode application. This is due to verification only being performed at the beginning of the routine allowing the userspace to change page permissions half way through the routine. A valid workaround is a rule to detect unauthorized loading of winpmem outside incident response operations.
Severity ?
7.3 (High)
CWE
- CWE-367 - Time-of-check Time-of-use (TOCTOU) Race Condition
