CVE-2026-64476

A flaw was found in the Linux kernel's vfio/pci driver. The disableidled3 flag, which controls device power states, was handled as a global module parameter instead of being latched per device. This improper handling could lead to unbalanced Power Management PM operations for devices already boun...

CVE-2026-64475
