In the Linux kernel, the following vulnerability has been resolved: ceph: fix memory leaks in ceph_mdsc_build_path() Add __putname() calls to error code paths that did not free the "path" pointer obtained by __getname(). If ownership of this pointer is not passed to the caller via path_info.path, the function must free it before returning.
