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