Copy Fail exploit lets 732 bytes hijack Linux systems and quietly grab root

A newly disclosed Linux kernel vulnerability called Copy Fail lets a normal user gain root access using just a 732-byte script. The exploit is simple, reliable, and works across major distributions like Ubuntu, RHEL, and SUSE. Even worse, it silently modifies the page cache instead of files on disk, making detection difficult and raising concerns for both local systems and containerized environments.
