Linux Kernel Vulnerabilities — Ubuntu Security Update (USN-8959-1)

USN-8959-1 is a large Ubuntu kernel security update correcting flaws across many subsystems — USB Gadget drivers, memory management, multiple-device handling and more — spanning thousands of backported kernel CVEs in one release. Update and reboot: sudo apt update && sudo apt upgrade, then restart into the new kernel. Given the breadth, treat it as the month's baseline kernel update for the affected Ubuntu flavors.

Mega-kernel updates roll up thousands of individual fixes — every unpatched subsystem flaw in the list is simultaneously closed, which is why this single update is the month's most impactful patch for Ubuntu hosts.

    • Häufig gestellte Fragen

    What is USN-8959-1?
    It is Ubuntu's consolidated kernel security update, correcting several thousand backported kernel CVEs across subsystems including USB Gadget drivers, memory management and multi-device handling. Aggregate CVSS 5.5 reflects the average of a very broad set.
    Why does one update list thousands of CVEs?
    Ubuntu's stable-branch kernels receive every relevant upstream backport in rolling batches — a single notice can carry thousands of individually numbered fixes. The update applies as one package upgrade.
    How do I apply it?
    Run sudo apt update && sudo apt upgrade and reboot into the new kernel; verify with uname -r. All subsystem fixes activate on reboot.
    Is this related to the NVIDIA Tegra and AX.25 kernel notices?
    Yes — USN-8959-1, the Tegra variant (USN-8960-series) and the AX.25 race-condition notice (USN-8961-1) are the same backport wave delivered per kernel flavor and hardware variant.
