CVE-2026-68172

A flaw was found in the Linux kernel, specifically within the huge_ptep_get() helper function for the arm64 architecture. When this function is provided with an unaligned virtual address, it can incorrectly process Page Table Entries (PTEs). This can lead to the kernel dereferencing invalid memory pointers, potentially allowing access to unowned physical memory and ultimately causing a system crash (Denial of Service).

This issue affects arm64 hugetlb pagemap. huge_ptep_get() does not handle unaligned addresses within contig hugetlb folios. arm64 systems with hugetlb only.
