linux-lowlatency, linux-lowlatency-hwe-6.8, linux-nvidia-tegra, linux-oracle 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-nvidia-tegra: Linux kernel for NVIDIA Tegra systems - linux-oracle: Linux kernel for Oracle Cloud systems - 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: - x86 architecture; - InfiniBand drivers; - Network drivers; - Mellanox network drivers; - File systems infrastructure; - IPv4 networking; - Network traffic control; - TCP network protocol; - B.A.T.M.A.N. meshing protocol; - IPv6 networking; - Multipath TCP; - Netfilter; - RxRPC session sockets; - SCTP protocol; - SMC sockets; (CVE-2026-43083, CVE-2026-43197, CVE-2026-43198, CVE-2026-43465, CVE-2026-46242, CVE-2026-46325, CVE-2026-46331, CVE-2026-52914, CVE-2026-52924, CVE-2026-52931, CVE-2026-53151, CVE-2026-53176, CVE-2026-53212, CVE-2026-53215, CVE-2026-53225, CVE-2026-53228, CVE-2026-53359) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS linux-image-6.8.0-1031-nvidia-tegra 6.8.0-1031.32 linux-image-6.8.0-1031-nvidia-tegra-rt 6.8.0-1031.32 linux-image-6.8.0-1059-oracle 6.8.0-1059.62 linux-image-6.8.0-1059-oracle-64k 6.8.0-1059.62 linux-image-6.8.0-137-lowlatency 6.8.0-137.137.1 linux-image-6.8.0-137-lowlatency-64k 6.8.0-137.137.1 linux-image-lowlatency 6.8.0-137.137.1 linux-image-lowlatency-6.8 6.8.0-137.137.1 linux-image-lowlatency-64k 6.8.0-137.137.1 linux-image-lowlatency-64k-6.8 6.8.0-137.137.1 linux-image-nvidia-tegra 6.8.0-1031.32 linux-image-nvidia-tegra-6.8 6.8.0-1031.32 linux-image-nvidia-tegra-rt 6.8.0-1031.32 linux-image-nvidia-tegra-rt-6.8 6.8.0-1031.32 linux-image-oracle-6.8 6.8.0-1059.62 linux-image-oracle-64k-6.8 6.8.0-1059.62 linux-image-oracle-64k-lts-24.04 6.8.0-1059.62 linux-image-oracle-lts-24.04 6.8.0-1059.62 Ubuntu 22.04 LTS linux-image-6.8.0-137-lowlatency 6.8.0-137.137.1~22.04.1 linux-image-6.8.0-137-lowlatency-64k 6.8.0-137.137.1~22.04.1 linux-image-lowlatency-6.8 6.8.0-137.137.1~22.04.1 linux-image-lowlatency-64k-6.8 6.8.0-137.137.1~22.04.1 linux-image-lowlatency-64k-hwe-22.04 6.8.0-137.137.1~22.04.1 linux-image-lowlatency-hwe-22.04 6.8.0-137.137.1~22.04.1 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.
