Summary
In the Linux kernel, the following vulnerability has been resolved: LoongArch: Fix panic caused by NULL-PMD in huge_pte_offset() ERROR INFO: CPU 25 Unable to handle kernel paging request at virtual address 0x0 ... Call Trace: [<900000000023c30c>] huge_pte_offset+0x3c/0x58 [<900000000057fd4c>] hugetlb_follow_page_mask+0x74/0x438 [<900000000051fee8>] __get_user_pages+0xe0/0x4c8 [<9000000000522414>] faultin_page_range+0x84/0x380 [<9000000000564e8c>] madvise_vma_behavior+0x534/0xa48 [<900000000056689c>] do_madvise+0x1bc/0x3e8 [<9000000000566df4>] sys_madvise+0x24/0x38 [<90000000015b9e88>] do_syscall+0x78/0x98 [<9000000000221f18>] handle_syscall+0xb8/0x158 In some cases, pmd may be NULL and rely on NULL as the return value for processing, so it is necessary to determine this situation here.
