If you've ever felt anxious about the security of your machine while you wait for a solution to some vulnerability, a proposed change to the Linux kernel may interest you. Pitched by Nvidia staff Sasha Levin, it's effectively a killswitch that could shut down some functions while waiting for a more official solution.
As spotted by The Information, Levin writes, "Killswitch lets a privileged operator make a chosen kernel function return a fixed value without executing its body, as a temporary mitigation for a security bug while a real fix is being prepared"
