Ubuntu Security Notice USN-7475-1
May 02, 2025

linux-xilinx-zynqmp vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-xilinx-zynqmp: Linux kernel for Xilinx ZynqMP processors

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:
  - iSCSI Boot Firmware Table Attributes driver;
  - GPU drivers;
  - Network drivers;
  - File systems infrastructure;
  - NTFS3 file system;
  - SMB network file system;
  - Network namespace;
  - Ethernet bridge;
  - Networking core;
  - Ethtool driver;
  - IPv6 networking;
  - Network traffic control;
  - VMware vSockets driver;
(CVE-2024-50248, CVE-2024-57798, CVE-2025-21702, CVE-2024-56651,
CVE-2024-26837, CVE-2025-21703, CVE-2024-46826, CVE-2025-21700,
CVE-2024-50256, CVE-2024-35864, CVE-2025-21756, CVE-2025-21993,
CVE-2024-26928, CVE-2024-56658, CVE-2025-21701)

Update instructions:

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

Ubuntu 22.04 LTS
  linux-image-5.15.0-1046-xilinx-zynqmp  5.15.0-1046.50
  linux-image-xilinx-zynqmp       5.15.0.1046.50

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.
