ubuntu

April 24, 2025

Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-intel-iotg-5.15: Linux kernel for Intel IoT platforms

Details:

Jann Horn discovered that the watch_queue event notification subsystem in

the Linux kernel contained an out-of-bounds write vulnerability. A local

attacker could use this to cause a denial of service (system crash) or

escalate their privileges. (CVE-2022-0995)

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;

- MIPS architecture;

- PowerPC architecture;

- RISC-V architecture;

- S390 architecture;

- SuperH RISC architecture;

- User-Mode Linux (UML);

- x86 architecture;

- Block layer subsystem;

- Cryptographic API;

- ACPI drivers;

- Drivers core;

- RAM backed block device driver;

- Virtio block driver;

- Data acquisition framework and drivers;

- Hardwar...

Update Instructions

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

Ubuntu 20.04 LTS
  linux-image-5.15.0-1077-intel-iotg  5.15.0-1077.83~20.04.1
  linux-image-intel               5.15.0.1077.83~20.04.1
  linux-image-intel-iotg          5.15.0.1077.83~20.04.1

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.
