Summary of Kernel and DPKG Updates for Ubuntu

As of September 24, 2025, several significant security updates have been released for various versions of Ubuntu Linux, addressing vulnerabilities primarily within the Linux kernel and the dpkg package management system. These updates are crucial for maintaining system integrity and addressing potential exploitations by attackers.

Key Updates:

1. Linux Kernel Vulnerabilities:
- Updates are available for various kernel versions including AWS, NVIDIA, Real-time, OEM, and Azure configurations.
- Notable security notices include:
- USN-7755-3: Fixes vulnerabilities in the Linux kernel for AWS systems.
- USN-7766-1: Addresses vulnerabilities in the Linux kernel for AWS and GCP systems.
- USN-7765-1: Pertains to vulnerabilities in the NVIDIA Linux kernel.
- USN-7764-1: General kernel vulnerabilities affecting multiple subsystems.
- USN-7767-1: Updates for Real-time kernel vulnerabilities.
- USN-7771-1: OEM kernel vulnerabilities.
- USN-7770-1: Azure kernel vulnerabilities.
- USN-7769-1: General vulnerabilities affecting multiple kernel configurations.

Each update includes specific CVEs (Common Vulnerabilities and Exposures) that detail the nature of the vulnerabilities and the subsystems affected, such as ARM architecture, network drivers, and memory management.

2. DPKG Vulnerability:
- USN-7768-1: Identifies a vulnerability in dpkg that could lead to disk space consumption if a specially crafted file is opened. This could potentially cause a denial of service.
- Updates are provided for Ubuntu versions 22.04 LTS, 24.04 LTS, and 25.04, correcting issues with the dpkg package management system.

Update Instructions:

For all the mentioned updates, users are advised to perform standard system updates. It is crucial to reboot the system after installing the updates to ensure that all changes take effect. Additionally, due to unavoidable ABI (Application Binary Interface) changes, users must recompile and reinstall any third-party kernel modules they may have installed.

Conclusion:

Keeping your Ubuntu system updated is essential to protect against vulnerabilities that could be exploited by attackers. Users should follow the provided notices to apply the latest patches and maintain system security.
