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.

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.
