In plain language
What this advisory means
Multiple security flaws were found in the Linux kernel used by Ubuntu on NVIDIA systems. These issues could allow attackers to compromise affected computers. The update fixes problems across many parts of the kernel, such as drivers and network components. Applying the update and rebooting will help protect your system.
Technical explanation
How the issue affects the environment
A range of vulnerabilities affecting the Linux kernel have been identified, impacting multiple subsystems including User-space API (UAPI), processor architectures (ARM32, ARM64, RISC-V, S390, x86), block layer, cryptographic APIs, various drivers (e.g., GPU, network, USB), filesystems, network protocols, kernel subsystems, and more. These issues potentially allow attackers to compromise system integrity or security. The update addresses these flaws by patching the kernel components accordingly. Due to an ABI (Application Binary Interface) change in the kernel update, all third-party kernel modules must be recompiled and reinstalled to ensure compatibility.
Operational impact
Why teams should care
If left unpatched, these vulnerabilities can be exploited, potentially leading to system compromise, data breaches, or disruption of services in environments running the affected Ubuntu Linux kernel. This risks organizational data confidentiality, integrity, and system availability. Timely update deployment is necessary to mitigate this risk.
Immediate action
Update your Ubuntu system's linux-nvidia kernel packages to version 7.0.0-1018.18 or later and reboot the system. Recompile and reinstall all third-party kernel modules due to an ABI change in the kernel update.
