Linus Torvalds kavatses avaldada Linuxi tuuma 6.13 v\u00e4ljaande sel p\u00fchap\u00e4eval, kuid t\u00f5en\u00e4oliselt pikendatakse 6.13 haru testimist n\u00e4dalaks, kuna esines probleeme muudatuste stabiilsusega, mille t\u00f6\u00f6tas v\u00e4lja Microsofti t\u00f6\u00f6taja ja mis v\u00f5eti novembris 6.13 harusse. Samuti m\u00e4rgitakse, et t\u00f5rke p\u00f5hjustanud plaastrit esitati ebatavaliselt \u2014 kuid see v\u00f5eti vastu, kuigi see ei saanud \u00fchtegi kinnitust (ACK) x86 arhitektuuri hooldajatelt, mis on tavaliste praktikate rikkumine. <\/p>\n

Patch lisas v\u00f5imaluse kasutada suuri m\u00e4lulehti ROX (Read Only Execute) re\u017eiimis, kui eraldatakse m\u00e4lu, mis on m\u00f5eldud t\u00e4itmiseks. ROX v\u00f5imaldab kasutada m\u00e4lus olevat t\u00e4itmisalget ainult lugemisre\u017eiimis, mis teeb teatud haavatavuste \u00e4rakasutamise keerulisemaks. S\u00fcdamikus 6.13 oli x86_64 s\u00fcsteemidel vaikimisi lubatud suurte t\u00e4idetavate m\u00e4lulehtede vahem\u00e4lu kasutamine, mis peegeldub ROX-ina. Muudatus lahendas probleemi ROX-re\u017eiimis lehtede kaardistamisega, mis olid veel t\u00e4ielikult moodustamata t\u00e4itmiseks, ja v\u00f5imaldas v\u00e4ltida ajutist ROX-lehtede kaardistamist kirjutamisre\u017eiimisse kuni s\u00fcdamiku moodulite t\u00f6\u00f6tamiseks ettevalmistamise l\u00f5petamiseni. <\/p>\n

6.13 versiooni tuuma l\u00f5ppfaasis tuvastas Intel'i insener vea, mis takistab tuuma korrektset \u00e4rkamist unesest m\u00f5nede Intel'i protsessoritega s\u00fclearvutites (n\u00e4iteks Alderlake mikroarhitektuuri p\u00f5hjal t\u00f6\u00f6tavate CPU-dega). Viga ilmus tuuma kompileerimisel Clang'i kompilaatoriga, kui CFI (Control Flow Integrity) kaitse re\u017eiim oli sisse l\u00fclitatud, mis takistab normip\u00e4rase t\u00f6\u00f6korra (control flow) rikkumist seoses eksploiteerimisega, mis muudab m\u00e4lu salvestatud funktsiooni osutajaid. Ajutise lahendusena soovitasid Intel'i ja AMD m\u00e4luhaldus x86 arhitektuuri eest vastutavad hooldajad 6.13 tuumas EXECMEM_ROX kasutamise keelata, kuni on valmis t\u00e4ielik pat\u0161, mis probleemi lahendab (esimene paranduse variant ei lahendanud probleemi).
