CWE
- CWE-782 - Exposed IOCTL with Insufficient Access Control
Summary
ThrottleStop.sys, a legitimate driver, exposes two IOCTL interfaces that allow arbitrary read and write access to physical memory via the MmMapIoSpace function. This insecure implementation can be exploited by a malicious user-mode application to patch the running Windows kernel and invoke arbitrary kernel functions with ring-0 privileges. The vulnerability enables local attackers to execute arbitrary code in kernel context, resulting in privilege escalation and potential follow-on attacks, such as disabling security software or bypassing kernel-level protections. ThrottleStop.sys version 3.0.0.0 and possibly others are affected. Apply updates per vendor instructions.

CWE
- CWE-782 - Exposed IOCTL with Insufficient Access Control
Summary
A potential insufficient access control vulnerability was reported in the Lenovo Dispatcher 3.0 and Dispatcher 3.1 drivers used by some Lenovo consumer notebooks that could allow an authenticated local user to execute code with elevated privileges. The Lenovo Dispatcher 3.2 driver is not affected. This vulnerability does not affect systems when the Windows feature Core Isolation Memory Integrity is enabled. Lenovo systems preloaded with Windows 11 have this feature enabled by default.
