Late last month, security researchers discovered a major vulnerability in the software that controls how PCs boot their operating systems. This is one of those issues that sounds scarier than it is. Fixing it will be a major process, especially for Linux system administrators and corporate IT organizations with a mixture of different PC vintages and manufacturers. The problem has been named BootHole, and it could affect up to a billion computers.

If you are running Linux, do your homework before rebooting or upgrading so you don’t make things worse. If you are running Windows, you’re better off waiting for Microsoft to issue a fix.  In the meantime, use basic security hygiene to avoid unwanted access to your machine.
