Ubuntu 5442-2: Linux kernel vulnerabilities
Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS: linux-image-5.4.0-1043-gkeop 5.4.0-1043.44 linux-image-5.4.0-1062-raspi 5.4.0-1062.70 linux-image-5.4.0-1073-oracle 5.4.0-1073.79 linux-image-gkeop 5.4.0.1043.46 linux-image-gkeop-5.4 5.4.0.1043.46 linux-image-oracle-lts-20.04 5.4.0.1073.73 linux-image-raspi 5.4.0.1062.96 linux-image-raspi2 5.4.0.1062.96 Ubuntu 18.04 LTS: linux-image-5.4.0-1023-ibm 5.4.0-1023.25~18.04.1 linux-image-5.4.0-1043-gkeop 5.4.0-1043.44~18.04.1 linux-image-5.4.0-1062-raspi 5.4.0-1062.70~18.04.1 linux-image-5.4.0-1073-oracle 5.4.0-1073.79~18.04.1 linux-image-5.4.0-1075-gcp 5.4.0-1075.80~18.04.1 linux-image-gcp 5.4.0.1075.58 linux-image-gkeop-5.4 5.4.0.1043.44~18.04.42 linux-image-ibm 5.4.0.1023.39 linux-image-oracle 5.4.0.1073.79~18.04.52 linux-image-raspi-hwe-18.04 5.4.0.1062.63 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
