CVE-2026-64157

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> netfs: Fix partial invalidation of streaming-write folio<br /> <br /> In netfs_invalidate_folio(), if the region of a partial invalidation<br /> overlaps the front (but not all) of a dirty write cached in a streaming<br /> write page (dirty, but not uptodate, with the dirty region tracked by a<br /> netfs_folio struct), the function modifies the dirty region - but<br /> incorrectly as it moves the region forward by setting the start to the<br /> start, not the end, of the invalidation region.<br /> <br /> Fix this by setting finfo-&gt;dirty_offset to the end of the invalidation<br /> region (iend).
