AI-suggested
Apply the official security update provided by Ubuntu in package version 5.15.0-1097.106+fips1 or later. After updating, reboot the system to activate the fixes. Due to an ABI change, recompile and reinstall all third-party kernel modules. Standard system upgrades will handle this automatically unless kernel metapackages were manually removed.
Description
Multiple security vulnerabilities were identified in the Linux kernel for the Azure FIPS variant, affecting network drivers, packet sockets, network traffic control, and the VMware vSockets driver. These flaws could potentially allow an attacker to compromise the system. A security update addressing these issues is available and requires a system reboot and recompilation of third-party kernel modules due to an ABI change.
