CVE-2026-64476

In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Latch disableidled3 per device When disableidled3 was introduced in vfio-pci, it directly manipulated the device power state with pcisetpowerstate. There were no refcounts to maintain or balanced operations, we could...

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...
