AI-suggested
A patch is available and users should update their Linux kernel packages to the fixed versions listed in the Ubuntu advisory USN-7764-1. After updating, a system reboot is required to apply the fixes. Due to an ABI change, recompilation and reinstallation of all third-party kernel modules is necessary to maintain system stability. Follow the vendor's update instructions carefully to ensure full remediation.
Description
Multiple security vulnerabilities were discovered in the Linux kernel affecting numerous subsystems and architectures. These flaws could potentially allow an attacker to compromise affected systems. The issues impact a wide range of kernel components including ARM and x86 architectures, various device drivers, networking stacks, memory management, and more. Ubuntu has released patches addressing these vulnerabilities in several kernel versions. Users are advised to update to the fixed versions and reboot to apply the changes. Due to ABI changes, recompilation of third-party kernel modules may be necessary.
