[PATCH openEuler-1.0-LTS] dhugetlb: isolate hwpoison hugepage when release
by Yongqiang Liu 23 Feb '23

23 Feb '23

From: Liu Shixin <liushixin2(a)huawei.com> hulk inclusion category: bugfix bugzilla: 46904, https://gitee.com/openeuler/kernel/issues/I6GSKP CVE: NA -------------------------------- For a hwpoison hugetlb page, the page will be freed firstly. If succeed, it will be dissolved and released to buddy system, then isolate the hwpoison page. For a hwpoison hugepage belong to dynamic hugetlb, we isolate the hugepage without dissolve it. Add a check in free_huge_page_to_dhugetlb_pool() to isolate the hwpoison hugepage directly. And keep HUGETLB_PAGE_DTOR after free to ensure the PageHuge() check return true in dissolve_free_huge_page().

[PATCH openEuler-1.0-LTS] mm/sharepool: Fix null-pointer-deference in sp_free_area

22 Feb '23

From: Wang Wensheng <wangwensheng4(a)huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6G76L CVE: NA ---------------------------------------------- When a process is deleted from a group, the process does not apply for memory from the shared group. Otherwise, the UAF problem occurs. We checked this, but it didn't do a good job of preventing sp_alloc and del_task concurrency. The process applies for memory after passing the check, which violates our requirements and causes problems. The solution is to place the checked code in the critical area to ensure that no memory can be allocated after the check is passed.
