Ubuntu 7381-1: Linux kernel (Low Latency) Security Advisory Updates

ubuntu
Calendar Grey March 27, 2025
Dist Ubuntu Esm H88
Several issues fixed in Ubuntu kernel, addressing threats such as denial of service and heap overflows. Update recommended.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-lowlatency-hwe-6.11: 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;

- MIPS architecture;

- PowerPC architecture;

- RISC-V architecture;

- S390 architecture;

- x86 architecture;

- Block layer subsystem;

- Compute Acceleration Framework;

- ACPI drivers;

- Drivers core;

- Ublk userspace block driver;

- Virtio block driver;

- Bluetooth drivers;

Update Instructions

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

Ubuntu 24.04 LTS
   linux-image-6.11.0-1011-lowlatency  6.11.0-1011.12~24.04.1
   linux-image-6.11.0-1011-lowlatency-64k  6.11.0-1011.12~24.04.1
   linux-image-lowlatency-64k-hwe-24.04  6.11.0-1011.12~24.04.1
   linux-image-lowlatency-hwe-24.04  6.11.0-1011.12~24.04.1

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.
