========================================================================== Ubuntu Security Notice USN-8148-3 April 02, 2026 linux-realtime, linux-realtime-6.8, linux-raspi-realtime 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-raspi-realtime: Linux kernel for Raspberry Pi Real-time systems - linux-realtime: Linux kernel for Real-time systems - linux-realtime-6.8: Linux kernel for Real-time systems 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: - Cryptographic API; - Netfilter; - Network traffic control; (CVE-2026-23060, CVE-2026-23074, CVE-2026-23111) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS linux-image-6.8.0-2041-raspi-realtime 6.8.0-2041.42 Available with Ubuntu Pro linux-image-6.8.1-1046-realtime 6.8.1-1046.47 Available with Ubuntu Pro linux-image-intel-iot-realtime 6.8.1-1046.47 Available with Ubuntu Pro linux-image-raspi-realtime 6.8.0-2041.42 Available with Ubuntu Pro linux-image-raspi-realtime-6.8 6.8.0-2041.42 Available with Ubuntu Pro linux-image-realtime 6.8.1-1046.47 Available with Ubuntu Pro linux-image-realtime-6.8.1 6.8.1-1046.47 Available with Ubuntu Pro Ubuntu 22.04 LTS linux-image-6.8.1-1046-realtime 6.8.1-1046.47~22.04.2 Available with Ubuntu Pro linux-image-realtime-6.8.1 6.8.1-1046.47~22.04.2 Available with Ubuntu Pro linux-image-realtime-hwe-22.04 6.8.1-1046.47~22.04.2 Available with Ubuntu Pro 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.
