An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: ARM64 architecture; Cryptographic API; Netfilter; Network traffic control Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: ARM64 architecture; Cryptographic API; Netfilter; Network traffic control Update instructions After a standard system update you need to reboot your computer to make all the necessary changes. Learn more about how to get the fixes. 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. The problem can be corrected by updating your system to the following package versions: Ubuntu Release Package Version 22.04 LTS jammy linux-image-5.15.0-1045-nvidia-tegra-igx – 5.15.0-1045.45
