  "details": "In the Linux kernel, the following vulnerability has been resolved:  configfs: unhash the dentry before dropping the item in rmdir  configfs_get_config_item() treats a hashed dentry as proof that sd-\u003es_element is a live config_item.  configfs_rmdir() breaks that: simple_rmdir() leaves the dentry hashed, the last reference to the item is dropped right after, and the dentry is only unhashed by d_delete() once -\u003ermdir() has returned.  configfs_symlink() resolves its target holding no lock on it, so get_target() can land in that window:    BUG: KASAN: slab-use-after-free in config_item_get+0x26/0x90    get_target fs/configfs/symlink.c:128 [inline]    configfs_symlink+0x4ab/0x1030 fs/configfs/symlink.c:185  Unhash in configfs_remove_dir(), while the item is still guaranteed to be there.  A reference obtained just before that stays harmless, as create_link() rechecks CONFIGFS_USET_DROPPING, already set by configfs_detach_prep().  Both configfs_unregister_subsystem() paths d_drop() after detaching, so this only makes rmdir match them.",
