N\u00eb versionin e Fedora Linux 45, i planifikuar p\u00ebr n\u00eb vjesht\u00ebn e vitit 2026, n\u00eb sistemet x86_64 pritet q\u00eb t\u00eb aktivizohet si parazgjedhje p\u00ebrdorimi i stak\u00ebs s\u00eb err\u00ebt (shadow stack) p\u00ebr t\u00eb bllokuar funksionimin e eksploit\u00ebve q\u00eb ndryshojn\u00eb adres\u00ebn e rikthimit t\u00eb funksioneve n\u00eb rast t\u00eb mbushjes s\u00eb tamponit n\u00eb stok. Mbrojtja pritet t\u00eb aktivizohet p\u00ebr t\u00eb gjitha aplikacionet dhe bibliotekat e nd\u00ebrtuara me ndihm\u00ebn e kompiler\u00ebve gcc (C, C++), clang (C, C++) dhe rustc (Rust). Plani ende nuk \u00ebsht\u00eb miratuar nga komiteti FESCo (Fedora Engineering Steering Committee), i cili \u00ebsht\u00eb p\u00ebrgjegj\u00ebs p\u00ebr aspektin teknik t\u00eb zhvillimit t\u00eb Fedora Linux. Iniciatori i p\u00ebrfshirjes s\u00eb stak\u00ebs s\u00eb err\u00ebt n\u00eb Fedora \u00ebsht\u00eb Arjun Shankar nga kompanis\u00eb Red Hat, i cili mbik\u00ebqyr paketat me glibc n\u00eb Fedora dhe RHEL.<\/p>\n
Mbrojtja realizohet duke p\u00ebrdorur mund\u00ebsit\u00eb harduerike t\u00eb procesor\u00ebve dhe p\u00ebrfshin at\u00eb q\u00eb, pas kalimit t\u00eb kontrollit n\u00eb funksion, adresat e kthimit ruhen nga procesori jo vet\u00ebm n\u00eb stekun e zakonsh\u00ebm, por gjithashtu n\u00eb nj\u00eb stek \"hije\", i cili nuk mund t\u00eb ndryshohet drejtp\u00ebrdrejt. Para dalje nga funksioni, adresa e kthimit nxirret nga steku i hijes dhe krahasonhet me adres\u00ebn e kthimit nga steku kryesor. N\u00ebse adresat nuk p\u00ebrputhen, gjenerohet nj\u00eb p\u00ebrjashtim q\u00eb bllokon situatat kur nj\u00eb shfryt\u00ebzim ka arritur t\u00eb rinovoj\u00eb adres\u00ebn n\u00eb stekun kryesor. Mekanizmi i stekut t\u00eb hijes p\u00ebrkrahhet q\u00eb nga gjenerata e 11-t\u00eb e procesor\u00ebve Intel (\"Tiger Lake\" dhe \"Rocket Lake\") dhe mikroarkitektura Zen3 n\u00eb procesor\u00ebt AMD.
