Description
In the Linux kernel, the following vulnerability has been resolved: LoongArch: mm: Add p?d_leaf() definitions When I do LTP test, LTP test case ksm06 caused panic at break_ksm_pmd_entry -> pmd_leaf (Huge page table but False) -> pte_present (panic) The reason is pmd_leaf() is not defined, So like commit 501b81046701 ("mips: mm: add p?d_leaf() definitions") add p?d_leaf() definition for LoongArch.

Executive Summary

This vulnerability is related to the Linux kernel on the LoongArch architecture. It occurs because the function pmd_leaf() was not defined, which caused a kernel panic during the LTP test case ksm06. Specifically, the panic happened at break_ksm_pmd_entry due to pmd_leaf being false and pte_present causing the panic. The issue was resolved by adding the missing pmd_leaf() definitions for LoongArch, similar to a previous fix for the MIPS architecture.

Impact Analysis

This vulnerability can cause the Linux kernel to panic (crash) during certain memory management operations on LoongArch systems, specifically when handling huge page tables. This can lead to system instability or downtime.
