Canonical Patches Linux Kernel Regression in Ubuntu 18.04 LTS, Update Now

On January 27th, Canonical released a major kernel security update for the Ubuntu 18.04 LTS (Bionic Beaver) operating system series, addressing no less than eleven vulnerabilities, seven of which affected the EXT4 file system implementation within the Linux kernel. The flaws affected Ubuntu 18.04 LTS and its derivatives. At that moment in time, users were urged to update their Ubuntu 18.04 LTS systems to the linux-image 4.15.0-44.47 kernel if they used Linux kernel 4.15, as well as to linux-image 4.18.0-14.15~18.04.1 if they used the Linux 4.18 kernel series. However, it would appear that the Linux 4.15 kernel update introduced an unwanted regression.
