In the Linux kernel, the following vulnerability has been resolved: jffs2: fix memory leak in jffs2_do_fill_super If jffs2_iget() or d_make_root() in jffs2_do_fill_super() returns an error, we can observe the following kmemleak report:

This is because the resources allocated in jffs2_sum_init() are not released. Call jffs2_sum_exit() to release these resources to solve the problem.
