CVE-2026-74591 mm/filemap: __filemap_add_folio() restore index before retrying

In the Linux kernel, the following vulnerability has been resolved: mm/filemap: filemapaddfolio restore index before retrying In filemapaddfolio's split-a-conflict loop, xassetorder is applied repeatedly: each application modifies xas.xaindex, rounding it down according to the splitorder attempte...

CVE-2026-74591

A race condition in the Linux kernel's __filemap_add_folio() function (in mm/filemap) allows a folio to be stored at an incorrect (intermediate rounded-down) xarray index. When the split-a-conflict retry path drops the lock for memory allocation and another thread resolves the conflict meanwhile,...
