CVE-2024-27036

CVE-2024-27036 affects the Linux kernel CIFS writeback path. The vulnerability arises when cifs_extend_writeback() considers an extra folio but would overrun the wsize, causing the xarray scanning loop to rely on xas_pause(), which advances the counter and can skip a page. The fix is to call xas_...
