AI-suggested

A security update is available and should be applied immediately. Users should upgrade to linux-azure kernel version 5.15.0-1097.106 or later and reboot their systems to complete the update. Due to an ABI change, all third-party kernel modules must be recompiled and reinstalled after the update. Follow the official Ubuntu security notice USN-7810-1 for detailed update instructions.

Description

Multiple security vulnerabilities were identified in the Linux kernel for the Azure platform affecting network drivers, packet sockets, network traffic control, and the VMware vSockets driver. These issues could potentially allow an attacker to compromise the system. A patch addressing these flaws is available in version 5.15.0-1097.106. Users must update and reboot their systems, and recompile any third-party kernel modules due to an ABI change.
