CVE-2026-90283

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.
