security advisorysecurity issuecriticalUbuntu 24.04, 22.04 LTS: USN-7167-2 - Critical Linux Kernel Issues
Several security issues were fixed in the Linux kernel.. ========================================================================== Ubuntu Security Notice USN-7167-2 January 07, 2025 linux-hwe-6.8, linux-lowlatency, linux-lowlatency-hwe-6.8 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 24.04 LTS - Ubuntu 22.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-lowlatency: Linux low latency kernel - linux-hwe-6.8: Linux hardware enablement (HWE) kernel - linux-lowlatency-hwe-6.8: Linux low latency 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: - Ext4 file system; - Network traffic control; - VMware vSockets driver; (CVE-2024-50264, CVE-2024-49967, CVE-2024-53057) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS linux-image-6.8.0-51-lowlatency 6.8.0-51.52.1 linux-image-6.8.0-51-lowlatency-64k 6.8.0-51.52.1 linux-image-lowlatency 6.8.0-51.52.1 linux-image-lowlatency-64k 6.8.0-51.52.1 linux-image-lowlatency-64k-hwe-24.04 6.8.0-51.52.1 linux-image-lowlatency-hwe-24.04 6.8.0-51.52.1 Ubuntu 22.04 LTS linux-image-6.8.0-51-generic 6.8.0-51.52~22.04.1 linux-image-6.8.0-51-generic-64k 6.8.0-51.52~22.04.1 linux-image-6.8.0-51-lowlatency 6.8.0-51.52.1~22.04.1 linux-image-6.8.0-51-lowlatency-64k 6.8.0-51.52.1~22.04.1 linux-image-generic-64k-hwe-22.04 6.8.0-51.52~22.04.1 linux-image-generic-hwe-22.04 6.8.0-51.52~22.04.1 linux-image-lowlatency-64k-hwe-22.04 6.8.0-51.52.1~22.04.1 linux-image-lowlatency-hwe-22.04 6.8.0-51.52.1~22.04.1 linux-image-oem-22.04 6.8.0-51.52~22.04.1 linux-image-oem-22.04a 6.8.0-51.52~22.04.1 linux-image-oem-22.04b 6.8.0-51.52~22.04.1 linux-image-oem-22.04c 6.8.0-51.52~22.04.1 linux-image-oem-22.04d 6.8.0-51.52~22.04.1 linux-image-virtual-hwe-22.04 6.8.0-51.52~22.04.1 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.

security advisorydebiankernel upgradeDebian 8 LTS: DLA-1424-1 Kernel Upgrade for Linux 4.9 Low Severity Advisory
Linux 4.9 has been packaged for Debian 8 as linux-4.9. This provides a supported upgrade path for systems that currently use kernel packages from the "jessie-backports" suite. . Package : linux-latest-4.9 Version : 80+deb9u5~deb8u1 Linux 4.9 has been packaged for Debian 8 as linux-4.9. This provides a supported upgrade path for systems that currently use kernel packages from the "jessie-backports" suite. However, "apt full-upgrade" will *not* automatically install the updated kernel packages. You should explicitly install one of the following metapackages first, as appropriate for your system: linux-image-4.9-686 linux-image-4.9-686-pae linux-image-4.9-amd64 linux-image-4.9-armmp linux-image-4.9-armmp-lpae linux-image-4.9-marvell For example, if the command "uname -r" currently shows "4.9.0-0.bpo.6-amd64", you should install linux-image-4.9-amd64. There is no need to upgrade systems using Linux 3.16, as that kernel version will also continue to be supported in the LTS period. Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS -- Ben Hutchings - Debian developer, member of kernel, installer and LTS teams .
