Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: mm/page_alloc: clear page->private in
 free_pages_prepare() Several subsystems (slub, shmem, ttm, etc.) use page->private but don't clear it
 before freeing pages. When these pages are later allocated as high-order pages and split via split_page(),
 tail pages retain stale page->private values. This causes a use-after-free in the swap subsystem. The swap
 code uses page->private to track swap count continuations, assuming freshly allocated pages have
 page->private == 0. When stale values are present, swap_count_continued() incorrectly assumes the
 continuation list is valid and iterates over uninitialized page->lru containing LIST_POISON values,
 causing a crash: KASAN: maybe wild-memory-access in range [0xdead000000000100-0xdead000000000107] RIP:
 0010:__do_sys_swapoff+0x1151/0x1860 Fix this by clearing page->private in free_pages_prepare(), ensuring
 all freed pages have clean state regardless of previous use. (CVE-2026-43303)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.613.40 or later.
