USN-7390-1: Linux kernel (Xilinx ZynqMP) vulnerabilities

Publication date

28 March 2025

Overview

Several security issues were fixed in the Linux kernel.

Releases

Packages

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;
  • 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...

Update instructions

After a standard system update you need to reboot your computer to make all the necessary changes.

Learn more about how to get the fixes.

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.

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

Ubuntu Release Package Version
22.04 jammy linux-image-5.15.0-1044-xilinx-zynqmp –  5.15.0-1044.48
linux-image-xilinx-zynqmp –  5.15.0.1044.48
