CVE-2026-64476

The CVE-2026-64476 vulnerability affects the Linux kernel vfio-pci driver. The root cause was improper handling of the disable_idle_d3 flag, which initially could be changed globally and influenced per-device power states via runtime_power management (PM). The issue arose because the vfio-pci mod...
