CVE 설명
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.
