- CVE-2026-70459: guard the parent_ndx consumer against an empty dir_flist so a crafted first incremental file list cannot reach an uninitialised heap slot (already blocked in els11 by the CVE-2026-53789 transfer-root rejection; added as defence in depth to match upstream's final state) - CVE-2026-70463: parse "auth users" with conf_strtok so the documented leading-comma form splits on commas alone; whitespace splitting tore an entry containing a space in two, so a :deny rule naming such a group never fired - CVE-2026-53798: reject an empty or non-numeric name-converter response instead of letting atol("") map an unknown name to uid/gid 0 - CVE-2026-53786: strip the module_dir prefix before checking a --filter merge file against the daemon filter list, so an anchored module-relative rule matches - CVE-2026-53791: honour a PROXY header only from a peer matching the new "proxy protocol hosts" parameter, so a direct client cannot spoof its source address and bypass hosts allow/deny. NOTE: fail-closed as upstream -- a daemon using "proxy protocol = true" must set "proxy protocol hosts" to the trusted proxy's address or connections will be refused
