## Overview

In the Linux kernel, the following vulnerability has been resolved:

hugetlbfs: release subpool on fill_super failure

hugetlbfs_fill_super() allocates a hugepage subpool when size or min_size
mount options are specified.  hugepage_new_subpool() may also reserve huge
pages for min_size.

If root dentry creation fails after the subpool is created, the failure
path frees the subpool with kfree().  This bypasses hugepage_put_subpool()
and can leave min_size reservations charged.

Use hugepage_put_subpool() on the failure path, matching the normal
put_super path.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
