Ubuntu Security Notice USN-7769-1
September 24, 2025

linux, linux-aws, linux-gcp, linux-gcp-6.14, linux-oracle, linux-realtime,
linux-riscv, linux-riscv-6.14 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 25.04
- Ubuntu 24.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux: Linux kernel
- linux-aws: Linux kernel for Amazon Web Services (AWS) systems
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-realtime: Linux kernel for Real-time systems
- linux-riscv: Linux kernel for RISC-V systems
- linux-gcp-6.14: Linux kernel for Google Cloud Platform (GCP) systems
- linux-riscv-6.14: Linux kernel for RISC-V systems

Details:

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
