Platform integrity loss via driver use-after-free
Published May 15, 2026 · Updated May 15, 2026
Use-after-free in AMD Secure Processor PCI drivers allows local users to corrupt platform state or crash Windows systems. AMD identifies improper input validation in the ASP PCI driver but does not disclose the affected request path or how it permits freed memory to be reused. A low-privileged local account is required; exploitation can alter platform integrity or terminate the operating system, without reported data disclosure.
