========================================================================== Ubuntu Security Notice USN-6707-3 March 25, 2024
linux-aws, linux-aws-6.5 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 23.10 - Ubuntu 22.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-aws-6.5: Linux kernel for Amazon Web Services (AWS) systems Details: Lonial Con discovered that the netfilter subsystem in the Linux kernel did not properly handle element deactivation in certain cases, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2024-1085) Notselwyn discovered that the netfilter subsystem in the Linux kernel did not properly handle verdict parameters in certain cases, leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2024-1086) 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: - Network drivers; - PWM drivers; (CVE-2024-26597, CVE-2024-26599) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 23.10: linux-image-6.5.0-1016-aws 6.5.0-1016.16 linux-image-aws 6.5.0.1016.16 Ubuntu 22.04 LTS: linux-image-6.5.0-1016-aws 6.5.0-1016.16~22.04.1 linux-image-aws 6.5.0.1016.16~22.04.1 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.
