Ubuntu 6921-1: Linux kernel Security Advisory Updates
Summary
A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 24.04 LTS Summary: Several security issues were fixed in the Linux kernel. 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-gke: Linux kernel for Google Container Engine (GKE) systems - linux-ibm: Linux kernel for IBM cloud systems - linux-nvidia: Linux kernel for NVIDIA systems - linux-oem-6.8: Linux kernel for OEM systems - linux-raspi: Linux kernel for Raspberry Pi systems Details: Benedict Schlüter, Supraja Sridhara, Andrin Bertschi, and Shweta Shinde discovered that an untrusted hypervisor could inject malicious #VC interrupts and compromise the security guarantees of AMD SEV-SNP. This flaw is known as WeSee. A local attacker in control of the hypervisor could use this to expose sensitive information or possibly execute arbitrary code in the trusted execution environment. (CVE-2024-25742) 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: - DMA engine subsystem; - HID subsystem; - I2C subsystem; - PHY drivers; - TTY drivers; - IPv4 networking; (CVE-2024-35990, CVE-2024-35997, CVE-2024-35992, CVE-2024-35984, CVE-2024-36008, CVE-2024-36016)
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS linux-image-6.8.0-1007-gke 6.8.0-1007.10 linux-image-6.8.0-1008-raspi 6.8.0-1008.8 linux-image-6.8.0-1009-ibm 6.8.0-1009.9 linux-image-6.8.0-1009-oem 6.8.0-1009.9 linux-image-6.8.0-1010-nvidia 6.8.0-1010.10 linux-image-6.8.0-1010-nvidia-64k 6.8.0-1010.10 linux-image-6.8.0-1011-gcp 6.8.0-1011.12 linux-image-6.8.0-1012-aws 6.8.0-1012.13 linux-image-6.8.0-39-generic 6.8.0-39.39 linux-image-6.8.0-39-generic-64k 6.8.0-39.39 linux-image-aws 6.8.0-1012.13 linux-image-gcp 6.8.0-1011.12 linux-image-generic 6.8.0-39.39 linux-image-generic-64k 6.8.0-39.39 linux-image-generic-64k-hwe-24.04 6.8.0-39.39 linux-image-generic-hwe-24.04 6.8.0-39.39 linux-image-generic-lpae 6.8.0-39.39 linux-image-gke 6.8.0-1007.10 linux-image-ibm 6.8.0-1009.9 linux-image-ibm-classic 6.8.0-1009.9 linux-image-ibm-lts-24.04 6.8.0-1009.9 linux-image-kvm 6.8.0-39.39 linux-image-nvidia 6.8.0-1010.10 linux-image-nvidia-64k 6.8.0-1010.10 linux-image-oem-24.04 6.8.0-1009.9 linux-image-oem-24.04a 6.8.0-1009.9 linux-image-raspi 6.8.0-1008.8 linux-image-virtual 6.8.0-39.39 linux-image-virtual-hwe-24.04 6.8.0-39.39 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.
