CVE-2026-0465

Privileged system crash via dangling driver pointer

Published Aug 11, 2026 · Updated Aug 11, 2026

Use-after-free in the Utility Driver for AMD Ryzen Master and its Monitoring SDK allows local users to crash Windows systems. The driver frees a global pointer without nulling it, and an IOCTL handler later reads through that dangling pointer. High privileges and a specific attack condition are required; the bounded impact is a system crash or denial of service, with no reported data exposure or modification.
