Dist Ubuntu Esm H88
Critical security advisory for Ubuntu Linux kernel vulnerabilities including AppArmor issues affecting system integrity.
Several security issues were fixed in the Linux kernel.

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.

This update corrects flaws in the following subsystems:

- PowerPC architecture;

- x86 architecture;

- Block layer subsystem;

- Cryptographic API;

- ACPI drivers;

- ATM drivers;

- Drivers core;

- Network block device driver;

- Bluetooth drivers;

- Character device driver;

- TPM device driver;

- Data acquis...

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.
