CVE-2023-53361 Details
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.
A vulnerability in the Linux kernel's memory management for the LoongArch architecture has been addressed. The issue arose because the pmd_leaf() function, which is crucial for handling huge page tables, was not defined. This omission led to a kernel panic during the LTP test case ksm06. The vulnerability has been resolved by adding the necessary p?d_leaf() definitions, similar to a previous fix for the MIPS architecture.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the patched version are available on the official Linux kernel website.
