========================================================================== Ubuntu Security Notice USN-5634-1 September 22, 2022 linux-oem-5.17 vulnerability ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 22.04 LTS Summary: The system could be made to crash if it received specially crafted network traffic. Software Description: - linux-oem-5.17: Linux kernel for OEM systems Details: Domingo Dirutigliano and Nicola Guerrera discovered that the netfilter subsystem in the Linux kernel did not properly handle rules that truncated packets below the packet header size. When such rules are in place, a remote attacker could possibly use this to cause a denial of service (system crash). Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS: linux-image-5.17.0-1017-oem 5.17.0-1017.18 linux-image-oem-22.04 5.17.0.1017.16 linux-image-oem-22.04a 5.17.0.1017.16 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.
