"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nvfio: Remove device debugfs before releasing devres\n\nVFIO device debugfs files created with debugfs_create_devm_seqfile()\nstore a devres allocated debugfs_devm_entry as inode private data.\nvfio_unregister_group_dev() currently calls vfio_device_del() before\nvfio_device_debugfs_exit(), but device_del() releases devres. 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."
