This can\nleave debugfs entries visible with stale inode private data while\nunregister waits for userspace references to drain.\n\nRemove the per-device debugfs tree before vfio_device_del().  The debugfs\nview is diagnostic only, so losing it at the start of unregister is\npreferable to preserving entries whose backing storage may already have\nbeen released.\n\nComplete the teardown by clearing the per-device debugfs root after\nremoval.  This matches the global debugfs root cleanup and prevents\nfuture users from mistaking a removed dentry for a live debugfs tree\nduring the remainder of unregister.","epss":{"date":"2026-11-10","percentile":0.07087,"score":0.00175},"exploits":[],"kev":null,"metrics":[{"score":5.5,"severity":"medium","source":"NVD: nvd@nist.gov","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1794506604620,"publishedAt":1784974652757,"references":[{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"],"url":"https://git.kernel.org/stable/c/6cc60b41d61657dc469893d14e8e55d160056ff1"},{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"],"url":"https://git.kernel.org/stable/c/a53109ffb6b5148e11a27fb7670355b92db12dd3"},{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"],"url":"https://git.kernel.org/stable/c/a5df401dc84f091e20b045560569f0736758fea7"},{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"],"url":"https://git.kernel.org/stable/c/dc7fe87de492ea7f33a72b78d26650b75bf37f4f"}],"remediation":[{"kind":"fix","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","text":"The reporting source identifies this reference as a patch.
