Ubuntu Security Notice USN-8200-3
May 11, 2026
linux-raspi, linux-raspi-5.4 vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-raspi: Linux kernel for Raspberry Pi systems
- linux-raspi-5.4: Linux kernel for Raspberry Pi systems
Details:
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
- ARM64 architecture;
- Cryptographic API;
- GPU drivers;
- I2C subsystem;
- Network traffic control;
(CVE-2022-49046, CVE-2024-46816, CVE-2025-37849, CVE-2026-23060,
CVE-2026-23074)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 20.04 LTS
linux-image-5.4.0-1140-raspi 5.4.0-1140.153
Available with Ubuntu Pro
linux-image-raspi 5.4.0.1140.171
Available with Ubuntu Pro
linux-image-raspi-5.4 5.4.0.1140.171
Available with Ubuntu Pro
linux-image-raspi2 5.4.0.1140.171
Available with Ubuntu Pro
Ubuntu 18.04 LTS
linux-image-5.4.0-1140-raspi 5.4.0-1140.153~18.04.1
Available with Ubuntu Pro
linux-image-raspi-5.4 5.4.0.1140.153~18.04.1
Available with Ubuntu Pro
linux-image-raspi-hwe-18.04 5.4.0.1140.153~18.04.1
Available with Ubuntu Pro
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.

linux-nvidia-tegra vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 24.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-nvidia-tegra: Linux kernel for NVIDIA Tegra systems
Details:
Josh Eads, Kristoffer Janke, Eduardo Vela Nava, Tavis Ormandy, and Matteo
Rizzo discovered that some AMD Zen processors did not properly verify the
signature of CPU microcode. This flaw is known as EntrySign. A privileged
attacker could possibly use this issue to cause load malicious CPU
microcode causing loss of integrity and confidentiality. (CVE-2024-36347)

[USN-8267-1] Linux kernel vulnerabilities
==========================================================================
Ubuntu Security Notice USN-8267-1
May 11, 2026
linux-azure, linux-azure-fips, linux-oracle vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-azure-fips: Linux kernel for Microsoft Azure Cloud systems with FIPS
- linux-azure: Linux kernel for Microsoft Azure Cloud systems
- linux-oracle: Linux kernel for Oracle Cloud 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, CVE-2026-23268, CVE-2026-23269, CVE-2026-23403,
CVE-2026-23404, CVE-2026-23405, CVE-2026-23410, CVE-2026-23411)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
- ARM64 architecture;
- Cryptographic API;
- GPU drivers;
- Network drivers;
- UDF file system;
- NFC subsystem;
- Network traffic control;
- Sun RPC protocol;
- XFRM subsystem;

Ubuntu Security Notice USN-8266-1
May 11, 2026
linux, linux-aws, linux-aws-fips, linux-aws-hwe, linux-azure-4.15,
linux-fips, linux-gcp, linux-gcp-4.15, linux-gcp-fips, linux-hwe,
linux-kvm, linux-oracle vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.04 LTS
- Ubuntu 16.04 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-aws-fips: Linux kernel for Amazon Web Services (AWS) systems with FIPS
- linux-azure-4.15: Linux kernel for Microsoft Azure Cloud systems
- linux-fips: Linux kernel with FIPS
- linux-gcp-4.15: Linux kernel for Google Cloud Platform (GCP) systems
- linux-gcp-fips: Linux kernel for Google Cloud Platform (GCP) systems with FIPS
- linux-kvm: Linux kernel for cloud environments
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-aws-hwe: Linux kernel for Amazon Web Services (AWS-HWE) systems
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-hwe: Linux hardware enablement (HWE) kernel
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, CVE-2026-23268, CVE-2026-23269, CVE-2026-23403,

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
- GPU drivers;
- Network drivers;
- Sun RPC protocol;
- XFRM subsystem;

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.
