Ubuntu 5390-1: Linux kernel vulnerabilities
Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS: linux-image-5.15.0-1003-ibm 5.15.0-1003.3 linux-image-5.15.0-1004-gcp 5.15.0-1004.7 linux-image-5.15.0-27-generic 5.15.0-27.28 linux-image-5.15.0-27-generic-64k 5.15.0-27.28 linux-image-5.15.0-27-generic-lpae 5.15.0-27.28 linux-image-5.15.0-27-lowlatency 5.15.0-27.28 linux-image-5.15.0-27-lowlatency-64k 5.15.0-27.28 linux-image-gcp 5.15.0.1004.5 linux-image-generic 5.15.0.27.30 linux-image-generic-64k 5.15.0.27.30 linux-image-generic-lpae 5.15.0.27.30 linux-image-ibm 5.15.0.1003.4 linux-image-lowlatency 5.15.0.27.28 linux-image-lowlatency-64k 5.15.0.27.28 linux-image-oem-20.04 5.15.0.27.30 linux-image-virtual 5.15.0.27.30 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.
