Ubuntu 20.04 LTS USN-7288-2 critical: Linux kernel heap overflow

ubuntu
Calendar Grey February 25, 2025
Dist Ubuntu Esm H88
The Ubuntu Security Announcement USN-7289-3 provides insights into recent patches for the Linux kernel, addressing critical vulnerabilities such as a significant buffer overflow.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-lowlatency-hwe-5.15: Linux low latency kernel

Details:

Attila Szász discovered that the HFS+ file system implementation in the

Linux Kernel contained a heap overflow vulnerability. An attacker could use

a specially crafted file system image that, when mounted, could cause a

denial of service (system crash) or possibly execute arbitrary code.

(CVE-2025-0927)

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;

- x86 architecture;

- Block layer subsystem;

- ACPI drivers;

- GPU drivers;

- HID subsystem;

- I2C subsystem;

- IIO ADC drivers;

- IIO subsystem;

- InfiniBand drivers;

- IOMMU subsystem;

- IRQ chip drivers;

- Multiple devices driver;

- Media drivers;

- Network drivers;

- STMicro...

Update Instructions

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

Ubuntu 20.04 LTS
  linux-image-5.15.0-133-lowlatency  5.15.0-133.143~20.04.1
  linux-image-5.15.0-133-lowlatency-64k  5.15.0-133.143~20.04.1
  linux-image-lowlatency-64k-hwe-20.04  5.15.0.133.143~20.04.1
  linux-image-lowlatency-hwe-20.04  5.15.0.133.143~20.04.1

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.
