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.

security advisoryheap overflowsystem updateUbuntu 22.04 LTS USN-7329-1 critical: kernel heap overflow
Several security issues were fixed in the Linux kernel.. ========================================================================== Ubuntu Security Notice USN-7329-1 March 05, 2025 linux-gcp, linux-gcp-5.15, linux-gke 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-gcp: Linux kernel for Google Cloud Platform (GCP) systems - linux-gke: Linux kernel for Google Container Engine (GKE) systems - linux-gcp-5.15: Linux kernel for Google Cloud Platform (GCP) systems Details: Attila Szász discovered that the HFS+ file system implementation in the Linux Kernel contained a heap overflow vulnerability. An attacker could use a specially crafted file system image that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2025-0927) 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: - Block layer subsystem; - Network drivers; (CVE-2024-50274, CVE-2024-53064, CVE-2024-56672) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS linux-image-5.15.0-1076-gke 5.15.0-1076.82 linux-image-5.15.0-1078-gcp 5.15.0-1078.87 linux-image-gcp-lts-22.04 5.15.0.1078.74 linux-image-gke 5.15.0.1076.75 linux-image-gke-5.15 5.15.0.1076.75 Ubuntu 20.04 LTS linux-image-5.15.0-1078-gcp 5.15.0-1078.87~20.04.1 linux-image-gcp 5.15.0.1078.87~20.04.1 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 updateshave been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed.
