Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 22.04 LTS
linux-image-5.15.0-1094-intel-iot-realtime 5.15.0-1094.96
Available with Ubuntu Pro
linux-image-intel-iot-realtime 5.15.0.1094.98
Available with Ubuntu Pro
linux-image-intel-iot-realtime-5.15 5.15.0.1094.98
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.

[USN-8096-5] Linux kernel (NVIDIA Tegra IGX) vulnerabilities
==========================================================================
Ubuntu Security Notice USN-8096-5
March 23, 2026
linux-nvidia-tegra-igx vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-nvidia-tegra-igx: Linux kernel for NVIDIA Tegra IGX 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.

Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 22.04 LTS
linux-image-5.15.0-1044-nvidia-tegra-igx 5.15.0-1044.44
linux-image-5.15.0-1044-nvidia-tegra-igx-rt 5.15.0-1044.44
linux-image-nvidia-tegra-igx 5.15.0.1044.46
linux-image-nvidia-tegra-igx-5.15 5.15.0.1044.46
linux-image-nvidia-tegra-igx-rt 5.15.0.1044.46
linux-image-nvidia-tegra-igx-rt-5.15 5.15.0.1044.46
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.

[USN-8095-4] Linux kernel (AWS) vulnerabilities
==========================================================================
Ubuntu Security Notice USN-8095-4
March 23, 2026
linux-aws-6.8 vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-aws-6.8: Linux kernel for Amazon Web Services (AWS) 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.

Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 22.04 LTS
linux-image-6.8.0-1050-aws 6.8.0-1050.53~22.04.1
linux-image-6.8.0-1050-aws-64k 6.8.0-1050.53~22.04.1
linux-image-aws 6.8.0-1050.53~22.04.1
linux-image-aws-6.8 6.8.0-1050.53~22.04.1
linux-image-aws-64k 6.8.0-1050.53~22.04.1
linux-image-aws-64k-6.8 6.8.0-1050.53~22.04.1
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.

[USN-8094-3] Linux kernel (Real-time) vulnerabilities
==========================================================================
Ubuntu Security Notice USN-8094-3
March 23, 2026
linux-realtime-6.17 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-realtime-6.17: Linux kernel for Real-time 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)
It was discovered that some AMD Zen 5 processors supporting RDSEED
instruction did not properly handle entropy, potentially resulting in the
consumption of insufficiently random values. A local attacker could
possibly use this issue to influence the values returned by the RDSEED
instruction causing loss of confidentiality and integrity. (CVE-2025-62626)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 24.04 LTS
linux-image-6.17.0-1008-realtime 6.17.0-1008.9~24.04.1
Available with Ubuntu Pro
linux-image-realtime-6.17 6.17.0-1008.9~24.04.1
Available with Ubuntu Pro
linux-image-realtime-hwe-24.04 6.17.0-1008.9~24.04.1
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.
