Back Linuxsecurity Ubuntu 25.10 Kernel Major Security Vulnerabilities USN-8029
A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 25.10 Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux: Linux kernel - linux-raspi: Linux kernel for Raspberry Pi systems - linux-realtime: 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: - ARM64 architecture; - MIPS architecture; - Nios II architecture; - PA-RISC architecture; - RISC-V architecture; - S390 architecture; - Sun Sparc architecture; - x86 architecture; - Xtensa architecture; - Block layer subsystem; - Cryptographic API; - Compute Acceleration Framework; - ACPI drivers; - Drivers core; - Network block device driver; - Bluetooth drivers; - Bus devices; - Hardware random number generator core; - Character device driver;

The problem can be corrected by updating your system to the following package versions: Ubuntu 25.10 linux-image-6.17.0-1006-realtime 6.17.0-1006.7 linux-image-6.17.0-1008-raspi 6.17.0-1008.8 linux-image-6.17.0-14-generic 6.17.0-14.14 linux-image-6.17.0-14-generic-64k 6.17.0-14.14 linux-image-generic 6.17.0-14.14 linux-image-generic-6.17 6.17.0-14.14 linux-image-generic-64k 6.17.0-14.14 linux-image-generic-64k-6.17 6.17.0-14.14 linux-image-raspi 6.17.0-1008.8 linux-image-raspi-6.17 6.17.0-1008.8 linux-image-realtime 6.17.0-1006.7 linux-image-realtime-6.17 6.17.0-1006.7 linux-image-virtual 6.17.0-14.14 linux-image-virtual-6.17 6.17.0-14.14 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.
