CVE-2026-64475

CVE-2026-64475 concerns the Linux kernel VFIO PCI subsystem. The issue arises from a re-order in a Fixes sequence where vfio_pci_vga_init() was displaced as the last failure point inside vfio_pci_core_register_device(), without an unwind for the VGA arbiter registration. In current kernels this i...

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...
