Dentro la corsa del kernel Linux che può trasformare un login locale in root
Un bug di durata nel controllo del traffico nel kernel Linux, tracciato come CVE-2026-53264, mostra come una vulnerabilità locale circoscritta possa diventare un problema di privilegi a livello di sistema, mentre l'IA entra sempre più nei flussi di lavoro della ricerca sugli exploit.
