========================================================================== Ubuntu Security Notice USN-8015-5 February 20, 2026
linux-lowlatency, linux-xilinx vulnerabilities ========================================================================== 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-lowlatency: Linux low latency kernel - linux-xilinx: Linux kernel for Xilinx 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; - SMB network file system; - io_uring subsystem; (CVE-2025-38561, CVE-2025-39698, CVE-2025-40019) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS linux-image-6.8.0-1022-xilinx 6.8.0-1022.23 linux-image-6.8.0-94-lowlatency 6.8.0-94.96.1 linux-image-6.8.0-94-lowlatency-64k 6.8.0-94.96.1 linux-image-lowlatency 6.8.0-94.96.1 linux-image-lowlatency-6.8 6.8.0-94.96.1 linux-image-lowlatency-64k 6.8.0-94.96.1 linux-image-lowlatency-64k-6.8 6.8.0-94.96.1 linux-image-xilinx 6.8.0.1022.23 linux-image-xilinx-6.8 6.8.0.1022.23 linux-image-xilinx-zynqmp 6.8.0.1022.23 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.
