  "title": "smb: client: discard post-EOF pagecache when extending a file via clone range",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  smb: client: discard post-EOF pagecache when extending a file via clone range  cifs_remap_file_range() discarded the pagecache only for the folios overlapping the destination region, so when a clone extends the file the folio straddling the old EOF - which may hold data dirtied past EOF through an mmap - was never dropped and became visible as file content once the file was extended.  Start the discard at the smaller of fstart and the old EOF.  i_size is still old here, so nothing past the old EOF is flushed to the server.",
