==========================================================================

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:

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:
   - GPU drivers;
   - SMB network file system;
   - Memory management;
   - Netfilter;
   - Network traffic control;
(CVE-2025-37890, CVE-2024-46787, CVE-2025-37798, CVE-2025-38000,
CVE-2025-37932, CVE-2025-38001, CVE-2025-37997, CVE-2024-50047,
CVE-2024-53051)

Update instructions:

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

Ubuntu 22.04 LTS
   linux-image-5.15.0-1051-xilinx-zynqmp  5.15.0-1051.55
   linux-image-xilinx-zynqmp       5.15.0.1051.54
   linux-image-xilinx-zynqmp-5.15  5.15.0.1051.54

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.
