Linus Torvalds inten\u021biona s\u0103 publice versiunea kernelului Linux 6.13 duminica aceasta, dar probabil c\u0103 testarea versiunii 6.13 va fi extins\u0103 cu o s\u0103pt\u0103m\u00e2n\u0103 din cauza problemelor de stabilitate ap\u0103rute \u00een modific\u0103rile preg\u0103tite de un angajat Microsoft \u0219i integrate \u00een ramura 6.13 \u00een noiembrie. De asemenea, se men\u021bioneaz\u0103 c\u0103 patch-ul care a cauzat e\u0219ecul a fost introdus \u00een mod neobi\u0219nuit \u2014 dar a fost acceptat, de\u0219i nu a primit niciun confirmare (ACK) din partea mentenatorilor arhitecturii x86, ceea ce reprezint\u0103 o \u00eenc\u0103lcare a practicilor acceptate. <\/p>\n

Patch-ul ad\u0103uga posibilitatea utiliz\u0103rii paginilor mari de memorie \u00een modul ROX (Read Only Execute) la alocarea memoriei destinate plas\u0103rii codului executabil. ROX permite utilizarea memoriei cu cod executabil \u00een modul doar pentru citire, ceea ce face mai dificil\u0103 exploatarea unor vulnerabilit\u0103\u021bi. \u00cen nucleul 6.13, pentru codul executabil al modulelor pe sistemele x86_64, utilizarea cache-ului de pagini mari de memorie executabil\u0103 a fost activat\u0103 implicit, reflectat\u0103 ca ROX. Modificarea rezolva problema cu maparea \u00een modul ROX a paginilor pentru codul executabil care nu era \u00eenc\u0103 complet format \u0219i permitea evitarea reproiect\u0103rii temporare a paginilor ROX \u00een modul de scriere p\u00e2n\u0103 la finalizarea preg\u0103tirii modulelor nucleului pentru operare. <\/p>\n

\u00cen etapa final\u0103 de testare a nucleului 6.13, un inginer de la Intel a descoperit o defec\u021biune care \u00eempiedic\u0103 nucleul s\u0103 ias\u0103 corect din modul de \u00eenvechire pe unele laptopuri cu procesoare Intel (de exemplu, cu CPU bazat pe microarhitectura Alderlake). Defec\u021biunea s-a manifestat la compilarea nucleului cu compilatorul Clang, activ\u00e2nd modul de protec\u021bie CFI (Control Flow Integrity), care blocheaz\u0103 \u00eenc\u0103lc\u0103rile ordinii normale de execu\u021bie (control flow) ca urmare a aplic\u0103rii exploit-urilor care modific\u0103 pointerii func\u021biilor stoca\u021bi \u00een memorie. Ca solu\u021bie temporar\u0103, men\u021bin\u0103torii de la Intel \u0219i AMD, care r\u0103spund de arhitectura x86, au propus dezactivarea utiliz\u0103rii EXECMEM_ROX \u00een nucleul 6.13, p\u00e2n\u0103 c\u00e2nd va fi preg\u0103tit \u0219i testat un patch complet care s\u0103 rezolve problema (prima variant\u0103 de corectare nu a rezolvat problema).
