The nfs_permission function in fs/nfs/dir.c in the NFS client implementation in the Linux kernel and earlier, when atomic_open is available, does not check execute (aka EXEC or MAY_EXEC) permission bits, which allows local users to bypass permissions and execute files, as demonstrated by files on an NFSv4 fileserver.
