  "description": "In the Linux kernel, the following vulnerability has been resolved:  ovl: keep err zero after successful ovl_cache_get()  ovl_iterate_merged() stores PTR_ERR(cache) in err before checking IS_ERR(cache). On success err holds the truncated cache pointer and can be returned as a bogus non-zero error.  The syzbot reproducer reaches this through overlay-on-overlay readdir:    getdents64     iterate_dir(outer overlay file)       ovl_iterate_merged()         ovl_cache_get()           ovl_dir_read_merged()             ovl_dir_read()               iterate_dir(inner overlay file)                 ovl_iterate_merged()  Only compute PTR_ERR(cache) on the error path.",
