CyberRota Analysis
AI-GeneratedThe Thesycon DPC Latency Checker driver on Windows systems is vulnerable to a denial-of-service attack, allowing local unprivileged users to trigger a Blue Screen of Death (BSOD) by exploiting an insecure IOCTL interface that fails to validate user-supplied pointers. This flaw can lead to arbitrary kernel memory access, resulting in system instability and crashes. Organizations using affected versions of this driver should prioritize patching to mitigate the risk of service disruption.

Original NVD Description
A vulnerability in the Thesycon DPC Latency Checker driver (dpc.sys) thru 1.4.0 allows local unprivileged users to cause a denial-of-service (BSOD) condition on Windows systems. The driver exposes an IOCTL interface (0x81772008) that accepts user-controlled input without validating pointers before passing them to kernel APIs. Specifically, it dereferences a user-supplied pointer and uses the resulting value in a call to ExSetTimerResolution, leading to an arbitrary kernel memory access. Exploiting this flaw results in a system crash.
