[PATCH openEuler-1.0-LTS 1/2] etmem:fix kasan slab-out-of-bounds in do_swapcache_reclaim
by Laibin Qiu 20 Jul '22

20 Jul '22

From: liubo <liubo254(a)huawei.com> euleros inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5GN7K CVE: NA -------------------------------- In the do_swapcache_reclaim interface, there is a slab-out-of-bounds kasan problem; The reason for the problem is that when list_for_each_entry_safe_reverse_from traverses the LRU linked list, it does not consider that next may be equal to the head address, which may lead to the head address being accessed as the page address, causing problems. In response to the above problems, add a judgment about whether pos is head.
