AI-suggested
A patch is available and users should update their Linux kernel packages to the fixed versions listed by Ubuntu (e.g., 6.8.0-78.78~22.04.1, 6.8.0-1035.38~22.04.1, etc.) and reboot the system to apply the updates. Due to an ABI change, recompilation and reinstallation of all third-party kernel modules are necessary after updating. Follow the Ubuntu security notice USN-7703-4 for detailed update instructions.
Description
Multiple security vulnerabilities were discovered in the Linux kernel affecting a wide range of subsystems and architectures. These issues could potentially allow an attacker to compromise the system. The affected components include various hardware architectures, drivers, network protocols, filesystems, and kernel subsystems. Ubuntu has released updates correcting these flaws in several kernel packages for different Ubuntu releases. Users are advised to update and reboot to apply the fixes.
