The system could be made to crash under certain conditions.. ========================================================================== Ubuntu Security Notice USN-7489-1 May 06, 2025 linux, linux-aws, linux-gcp, linux-gcp-6.11, linux-hwe-6.11, linux-lowlatency, linux-lowlatency-hwe-6.11, linux-oracle, linux-raspi vulnerability ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 24.10 - Ubuntu 24.04 LTS Summary: The system could be made to crash under certain conditions. Software Description: - linux: Linux kernel - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems - linux-lowlatency: Linux low latency kernel - linux-oracle: Linux kernel for Oracle Cloud systems - linux-raspi: Linux kernel for Raspberry Pi systems - linux-gcp-6.11: Linux kernel for Google Cloud Platform (GCP) systems - linux-hwe-6.11: Linux hardware enablement (HWE) kernel - linux-lowlatency-hwe-6.11: Linux low latency kernel Details: A security issue was discovered in the Linux kernel. An attacker could possibly use this to compromise the system. This update corrects flaws in the following subsystems: - Timer subsystem; (CVE-2025-21813) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 24.10 linux-image-6.11.0-1012-raspi 6.11.0-1012.12 linux-image-6.11.0-1013-aws 6.11.0-1013.14 linux-image-6.11.0-1013-lowlatency 6.11.0-1013.14 linux-image-6.11.0-1013-lowlatency-64k 6.11.0-1013.14 linux-image-6.11.0-1014-gcp 6.11.0-1014.14 linux-image-6.11.0-1014-gcp-64k 6.11.0-1014.14 linux-image-6.11.0-1015-oracle 6.11.0-1015.16 linux-image-6.11.0-1015-oracle-64k 6.11.0-1015.16 linux-image-6.11.0-25-generic 6.11.0-25.25 linux-image-6.11.0-25-generic-64k 6.11.0-25.25 linux-image-aws 6.11.0-1013.14 linux-image-gcp 6.11.0-1014.14 linux-image-gcp-64k 6.11.0-1014.14 linux-image-generic 6.11.0-25.25 linux-image-generic-64k 6.11.0-25.25 linux-image-lowlatency 6.11.0-1013.14 linux-image-lowlatency-64k 6.11.0-1013.14 linux-image-oracle 6.11.0-1015.16 linux-image-oracle-64k 6.11.0-1015.16 linux-image-raspi 6.11.0-1012.12 linux-image-virtual 6.11.0-25.25 Ubuntu 24.04 LTS linux-image-6.11.0-1013-lowlatency 6.11.0-1013.14~24.04.1 linux-image-6.11.0-1013-lowlatency-64k 6.11.0-1013.14~24.04.1 linux-image-6.11.0-1014-gcp 6.11.0-1014.14~24.04.1 linux-image-6.11.0-1014-gcp-64k 6.11.0-1014.14~24.04.1 linux-image-6.11.0-25-generic 6.11.0-25.25~24.04.1 linux-image-6.11.0-25-generic-64k 6.11.0-25.25~24.04.1 linux-image-gcp 6.11.0-1014.14~24.04.1 linux-image-gcp-64k 6.11.0-1014.14~24.04.1 linux-image-generic-64k-hwe-24.04 6.11.0-25.25~24.04.1 linux-image-generic-hwe-24.04 6.11.0-25.25~24.04.1 linux-image-lowlatency-64k-hwe-24.04 6.11.0-1013.14~24.04.1 linux-image-lowlatency-hwe-24.04 6.11.0-1013.14~24.04.1 linux-image-virtual-hwe-24.04 6.11.0-25.25~24.04.1 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.
