Linux kernel - Denial of Service via Missing p?d_leaf() Definitions

Title source: llm
STIX 2.1

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.
