Ubuntu 20.04 LTS: USN-7119-1 critical: Kernel integer overflow

ubuntu
Calendar Grey November 20, 2024
Scroller Ubuntu
Ubuntu 20.04 LTS has received critical updates to the Linux kernel, mitigating various security vulnerabilities and reinforcing overall system robustness.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-iot: Linux kernel for IoT platforms

Details:

Ziming Zhang discovered that the VMware Virtual GPU DRM driver in the Linux

kernel contained an integer overflow vulnerability. A local attacker could

use this to cause a denial of service (system crash). (CVE-2022-36402)

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;

- PowerPC architecture;

- User-Mode Linux (UML);

- x86 architecture;

- Block layer subsystem;

- Cryptographic API;

- Android drivers;

- Serial ATA and Parallel ATA drivers;

- ATM drivers;

- Drivers core;

- CPU frequency scaling framework;

- Device frequency scaling framework;

- GPU drivers;

- HID subsystem;

- Hardware monitoring drivers;

- InfiniBand driver...

Update Instructions

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 20.04 LTS
   linux-image-5.4.0-1044-iot      5.4.0-1044.45

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.
