Several security issues were fixed in the Linux kernel.. ========================================================================== Ubuntu Security Notice USN-7076-1 October 17, 2024 linux-azure, linux-azure-5.15 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 22.04 LTS - Ubuntu 20.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-azure: Linux kernel for Microsoft Azure Cloud systems - linux-azure-5.15: Linux kernel for Microsoft Azure cloud systems Details: 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: - Microsoft Azure Network Adapter (MANA) driver; - Watchdog drivers; - Netfilter; - Network traffic control; (CVE-2024-27397, CVE-2024-45016, CVE-2024-45001, CVE-2024-38630) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS linux-image-5.15.0-1074-azure 5.15.0-1074.83 linux-image-azure-lts-22.04 5.15.0.1074.72 Ubuntu 20.04 LTS linux-image-5.15.0-1074-azure 5.15.0-1074.83~20.04.1 linux-image-azure 5.15.0.1074.83~20.04.1 linux-image-azure-cvm 5.15.0.1074.83~20.04.1 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.
