  "description": "In the Linux kernel, the following vulnerability has been resolved:\n\nconfigfs: unhash the dentry before dropping the item in rmdir\n\nconfigfs_get_config_item() treats a hashed dentry as proof that\nsd->s_element is a live config_item.  configfs_rmdir() breaks that:\nsimple_rmdir() leaves the dentry hashed, the last reference to the item is\ndropped right after, and the dentry is only unhashed by d_delete() once\n->rmdir() has returned.  configfs_symlink() resolves its target holding no\nlock on it, so get_target() can land in that window:\n\n  BUG: KASAN: slab-use-after-free in config_item_get+0x26/0x90\n   get_target fs/configfs/symlink.c:128 [inline]\n   configfs_symlink+0x4ab/0x1030 fs/configfs/symlink.c:185\n\nUnhash in configfs_remove_dir(), while the item is still guaranteed to be\nthere.  A reference obtained just before that stays harmless, as\ncreate_link() rechecks CONFIGFS_USET_DROPPING, already set by\nconfigfs_detach_prep().  Both configfs_unregister_subsystem() paths\nd_drop() after detaching, so this only makes rmdir match them.",
