Canonical Outs Kernel Update for Ubuntu 19.10 and 18.04 LTS Systems Running Linux 5.3

After releasing kernel updates for Ubuntu 18.04 LTS and 16.04 LTS, as well as Ubuntu 20.04 LTS, Canonical now also published a kernel security update for Ubuntu 19.10 (Eoan Ermine) and Ubuntu 18.04.4 LTS (Bionic Beaver) systems that use Linux kernel 5.3 to fix eight vulnerabilities. The issues fixed in this security update are a race condition (CVE-2019-19769) discovered by Tristan Madani in Linux kernel’s file locking implementation, which could allow a local attacker to either expose sensitive information or cause a denial of service.
