  "details": "In the Linux kernel, the following vulnerability has been resolved:  configfs: pin the symlink target's dirent instead of chasing -\u003eci_dentry  create_link() reads the target's configfs_dirent from item-\u003eci_dentry-\u003ed_fsdata, relying on the item reference taken by get_target().  That reference pins the item, not its dentry: the dentry is pinned by DCACHE_PERSISTENT, which configfs_remove_dir() releases via simple_rmdir() while the item is still alive.  A symlink racing with rmdir of its target can therefore find -\u003eci_dentry freed and its dirent released, triggering WARN_ON(!atomic_read(\u0026sd-\u003es_count)) in configfs_get().  Take the dirent in get_target() as well, under -\u003ed_lock and atomically with the item reference, and pass it down to create_link().  A hashed dentry has not been killed yet, so its -\u003ed_fsdata reference keeps the dirent alive there.",
