Kernel-memory disclosure via uninitialized PMF resource
Published May 15, 2026 · Updated May 15, 2026
Use of uninitialized memory in AMD Platform Management Framework allows local users to disclose kernel memory or interrupt service. The PMF driver exposes a kernel-memory resource before initializing it, permitting reads of residual kernel data. Local low-privileged access is required; the documented effects are limited to kernel-memory disclosure and availability loss.
