SECURITY UPDATE: code injection in the netrw plugin via the mf
(mark file) command: s:NetrwMarkFile() embedded the marked filename
into a filter() expression by string concatenation, so a crafted
filename containing vimscript (e.g. nested execute()) was evaluated
when the user marked it in a netrw listing.
debian/patches/CVE-2026-43961.patch: reference the filename
variable directly in the filter() expression instead of
concatenating it, in runtime/autoload/netrw.vim; matches upstream
patch 9.2.0480.
