CVE-2026-64473

Summary (CVE-2026-64473) : In the Linux kernel, VFIO debugfs teardown was reordered to fix a use-after-free-like state where per-device debugfs entries could remain visible with stale inode data after unregister. The root cause was that vfio_unregister_group_dev() called vfio_device_del() before ...
