Summary of Linux Kernel Updates for Ubuntu
As of August 12, 2025, several important kernel updates have been released for Ubuntu Linux to address various security vulnerabilities:
1. USN-7682-5: This notice pertains to vulnerabilities in the Linux kernel affecting Ubuntu 24.04 LTS and 22.04 LTS. Key components updated include:
- linux-gcp-6.8: Targeted for Google Cloud Platform systems.
- linux-raspi: Designed for Raspberry Pi systems.
The update corrects security flaws, particularly in network traffic control, which could potentially be exploited by attackers (CVE-2025-38083, CVE-2025-37797).
For Ubuntu 24.04 LTS, users are advised to update to specific package versions for the raspberry and GCP images. The same applies to Ubuntu 22.04 LTS with slightly different package versions.
2. USN-7681-3: This notice addresses vulnerabilities in the Linux kernel for Oracle Cloud systems (linux-oracle-6.14) affecting Ubuntu 24.04 LTS. Similar to the previous update, it fixes security issues in network traffic control (CVE-2025-38083). Users must also update to specified package versions.
- Users are cautioned that due to an ABI change, kernel updates come with a new version number, necessitating the recompilation and reinstallation of any third-party kernel modules.
Additionally, users who rely on third-party modules should maintain a record of their installations to ensure compatibility after kernel updates. This proactive approach can help avoid system issues following upgrades.
For organizations using Ubuntu in production environments, consider implementing automated update mechanisms or scheduled maintenance windows to facilitate timely updates without disrupting operations

Update Instructions
- After performing a standard system update, a reboot is required to apply the changes.- Users are cautioned that due to an ABI change, kernel updates come with a new version number, necessitating the recompilation and reinstallation of any third-party kernel modules.
Additional Information
For those needing more details, the updates can be referenced at Ubuntu's security notice pages, and package information can be found on Launchpad.Extended Information
It's crucial for users to stay proactive about system updates, especially concerning security vulnerabilities that could enable unauthorized access or compromise system integrity. Regularly reviewing the Ubuntu security notices and applying updates promptly can significantly reduce the risk of potential exploitation.Additionally, users who rely on third-party modules should maintain a record of their installations to ensure compatibility after kernel updates. This proactive approach can help avoid system issues following upgrades.
