AI-suggested
Until a fix is available, restrict local access to trusted users only to prevent exploitation.
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.
Impact
Exploitation of this vulnerability allows a local unprivileged user to cause a denial-of-service by crashing the system (BSOD). There is no indication of confidentiality or integrity impact. The CVSS score is 5.5 (medium severity) reflecting the local attack vector and denial-of-service impact only.
