Important patch for Ubuntu 22.04 LTS resolving several kernel vulnerabilities, strengthening security and overall system robustness.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

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

Details:

Michael Randrianantenaina discovered that the Bluetooth driver in the Linux

Kernel contained an improper access control vulnerability. A nearby

attacker could use this to connect a rougue device and possibly execute

arbitrary code. (CVE-2024-8805)

It was discovered that the CIFS network file system implementation in the

Linux kernel did not properly verify the target namespace when handling

upcalls. An attacker could use this to expose sensitive information.

(CVE-2025-2312)

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;

- PowerPC architecture;

- x86 architecture;

- Block layer subsystem;

- ACPI drivers;

- Network block device driver;

Update Instructions

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

Ubuntu 22.04 LTS
   linux-image-5.15.0-1050-xilinx-zynqmp  5.15.0-1050.54
   linux-image-xilinx-zynqmp       5.15.0.1050.53

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.
