AI-suggested

A patch is available and should be applied immediately by updating to the fixed Linux kernel versions listed in the vendor advisory USN-7682-1. After updating, a system reboot is required to activate the fixes. Due to an ABI change in the kernel update, all third-party kernel modules must be recompiled and reinstalled to ensure compatibility.

Description

Multiple security vulnerabilities were identified in the Linux kernel, specifically affecting the network traffic control subsystem. These flaws could potentially allow an attacker to compromise affected systems. The issues have been addressed in updated Linux kernel versions, and users are advised to apply these updates and reboot their systems. Due to an ABI change, recompilation of third-party kernel modules may be necessary after updating.
