In the Linux kernel, the following vulnerability has been resolved:
fs: autofs: fix memory leak in autofs_fill_super()
In autofs_fill_super(), we create a new inode using
autofs_new_ino(), however, if we fail to create root_inode,
(that is, root_inode failure path), we return -ENOMEM without
freeing the new inode(ino) that we created causing a memory leak.
Fix this by adding autofs_free_ino() to free the inode we created
in root_inode failure path before returning ENOMEM.
