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-raspi: Linux kernel for Raspberry Pi systems - linux-aws-6.14: Linux kernel for Amazon Web Services (AWS) systems - linux-hwe-6.14: Linux hardware enablement (HWE) kernel 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: - Cryptographic API; - Media drivers; - Netfilter; - TLS protocol; (CVE-2025-39946, CVE-2025-39964, CVE-2025-39993, CVE-2025-40018) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 25.04 linux-image-6.14.0-1018-aws 6.14.0-1018.18 linux-image-6.14.0-1018-aws-64k 6.14.0-1018.18 linux-image-6.14.0-1019-raspi 6.14.0-1019.19 linux-image-6.14.0-1021-gcp 6.14.0-1021.22 linux-image-6.14.0-1021-gcp-64k 6.14.0-1021.22 linux-image-6.14.0-37-generic 6.14.0-37.37 linux-image-6.14.0-37-generic-64k 6.14.0-37.37 linux-image-aws 6.14.0-1018.18 linux-image-aws-6.14 6.14.0-1018.18 linux-image-aws-64k 6.14.0-1018.18 linux-image-aws-64k-6.14 6.14.0-1018.18 linux-image-gcp 6.14.0-1021.22 linux-image-gcp-6.14 6.14.0-1021.22 linux-image-gcp-64k 6.14.0-1021.22 linux-image-gcp-64k-6.14 6.14.0-1021.22 linux-image-generic 6.14.0-37.37 linux-image-generic-6.14 6.14.0-37.37 linux-image-generic-64k 6.14.0-37.37 linux-image-generic-64k-6.14 6.14.0-37.37 linux-image-raspi 6.14.0-1019.19 linux-image-raspi-6.14 6.14.0-1019.19 linux-image-virtual 6.14.0-37.37 linux-image-virtual-6.14 6.14.0-37.37 Ubuntu 24.04 LTS linux-image-6.14.0-1018-aws 6.14.0-1018.18~24.04.1 linux-image-6.14.0-1018-aws-64k 6.14.0-1018.18~24.04.1 linux-image-6.14.0-37-generic 6.14.0-37.37~24.04.1 linux-image-6.14.0-37-generic-64k 6.14.0-37.37~24.04.1 linux-image-aws 6.14.0-1018.18~24.04.1 linux-image-aws-6.14 6.14.0-1018.18~24.04.1 linux-image-aws-64k 6.14.0-1018.18~24.04.1 linux-image-aws-64k-6.14 6.14.0-1018.18~24.04.1 linux-image-generic-6.14 6.14.0-37.37~24.04.1 linux-image-generic-64k-6.14 6.14.0-37.37~24.04.1 linux-image-generic-64k-hwe-24.04 6.14.0-37.37~24.04.1 linux-image-generic-hwe-24.04 6.14.0-37.37~24.04.1 linux-image-virtual-6.14 6.14.0-37.37~24.04.1 linux-image-virtual-hwe-24.04 6.14.0-37.37~24.04.1 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.
