Linux kernel maintainers suggest a ‘kill switch’ to protect systems until a zero-day vulnerability is patched

Linux server admins may get the ability to turn off a vulnerable function in the OS kernel until a patch for a zero-day vulnerability is ready, if a proposal from a kernel developer and maintainer is accepted by the open source community. The idea of a kill switch for privileged operators has been suggested by Sasha Levin , a distinguished engineer at Nvidia and co-maintainer of the long-term support and stable Linux kernel trees, as a mitigation when a security hole is discovered.
