CVE-2024-56628 addresses a vulnerability in the Linux kernel specific to the LoongArch architecture involving the handling of huge page table entries (huge_pte). The issue caused errors during memory management self-tests, leading to bad page states and kernel warnings. The flaw stemmed from improper handling of invalid huge page table entries, which should be marked with a specific invalid_pte_table or a single _PAGE_HUGE bit rather than zero. This fix aligns the handling of huge page table entries with the behavior of page middle directory (pmd) entries to prevent invalid memory states.
