Earlier this month, on July 2, Canonical released a Linux kernel security update for Ubuntu 18.04 LTS (Bionic Beaver) users, addressing a total of six security vulnerabilities, one of which introduced a regression also causing boot failures, though it doesn’t appear to be limited to AMD processors only, but also to Intel machines. Now, the company behind one of the most popular Linux-based operating system released new kernel updates to fix the regression causing boot failures on 64-bit machines, as well as for OEM processors and systems running on Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and other cloud environments.
