Several security issues were fixed in the Linux kernel.

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-azure: Linux kernel for Microsoft Azure Cloud 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: - ARM32 architecture; - ARM64 architecture; - M68K architecture; - OpenRISC architecture; - PowerPC architecture; - RISC-V ar...

Update Instructions

The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS linux-image-6.8.0-1012-azure 6.8.0-1012.14 linux-image-6.8.0-1012-azure-fde 6.8.0-1012.14 linux-image-azure 6.8.0-1012.14 linux-image-azure-fde 6.8.0-1012.14 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.
