  "details": "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.",
