USN-8851-2: Linux kernel (Raspberry Pi) vulnerabilities

Publisher update

The brief

Canonical's USN-8851-2 supplies fixes for Ubuntu 18.04 LTS systems using the Raspberry Pi 5.4 kernel. It addresses vulnerabilities in NFS server code, IPv6 networking and Netfilter that Canonical says could permit system compromise. The Ubuntu Pro update includes linux-image-5.4.0-1147-raspi version 5.4.0-1147.160~18.04.1. A reboot completes installation, and the changed kernel ABI requires rebuilding installed third-party kernel modules.
