CVE-2026-98685

The Linux kernel contains a vulnerability in the smb client where the cifs_remap_file_range() function fails to correctly discard the pagecache when extending a file via a clone range. Specifically, folios straddling the old EOF (which might contain data dirtied past the EOF via an mmap ) were no...

CVE-2026-98683

The Linux kernel contains a vulnerability in the SMB client component. The smb3_zero_range() function, which emulates FALLOC_FL_ZERO_RANGE, fails to unconditionally flush dirty data before invalidating the page cache and issuing FSCTL_SET_ZERO_DATA to the server. This occurs specifically for inte...
