Описание
In the Linux kernel, the following vulnerability has been resolved:
userns and mnt_idmap leak in open_tree_attr(2)
Once want_mount_setattr() has returned a positive, it does require finish_mount_kattr() to release ->mnt_userns. Failing do_mount_setattr() does not change that.
As the result, we can end up leaking userns and possibly mnt_idmap as well.
