Ubuntu Security Notice USN-8096-1
March 16, 2026
linux, linux-aws, linux-gcp, linux-gkeop, linux-ibm, linux-ibm-5.15,
linux-intel-iotg, linux-kvm, linux-lowlatency, linux-nvidia,
linux-nvidia-tegra, linux-nvidia-tegra-5.15, linux-oracle,
linux-xilinx-zynqmp vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
- Ubuntu 20.04 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-gkeop: Linux kernel for Google Container Engine (GKE) systems
- linux-ibm: Linux kernel for IBM cloud systems
- linux-intel-iotg: Linux kernel for Intel IoT platforms
- linux-kvm: Linux kernel for cloud environments
- linux-lowlatency: Linux low latency kernel
- linux-nvidia: Linux kernel for NVIDIA systems
- linux-nvidia-tegra: Linux kernel for NVIDIA Tegra systems
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-xilinx-zynqmp: Linux kernel for Xilinx ZynqMP processors
- linux-ibm-5.15: Linux kernel for IBM cloud systems
- linux-nvidia-tegra-5.15: Linux kernel for NVIDIA Tegra systems
Details:
Qualys discovered that several vulnerabilities existed in the AppArmor
Linux kernel Security Module (LSM). An unprivileged local attacker could
use these issues to load, replace, and remove arbitrary AppArmor profiles
causing denial of service, exposure of sensitive information (kernel
memory), local privilege escalation, or possibly escape a container.
(LP: #2143853)
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.
