Ubuntu 22.04 Xilinx ZynqMP Major Security Vulnerabilities USN-8528-1

ubuntu
Calendar Grey July 10, 2026
Dist Ubuntu Esm H88
Significant security updates for the Ubuntu kernel address multiple critical issues that could lead to privilege escalation.
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:

It was discovered that the Linux kernel algif_aead module did not properly

handle in-place cryptographic operations. This flaw is known as Copy Fail.

A local attacker could use this to escalate privileges, or possibly escape

a container. (CVE-2026-31431)

It was discovered that the Linux kernel did not properly handle shared page

fragments during socket buffer operations, collectively known as Dirty

Frag. A logic flaw existed in the XFRM ESP-in-TCP subsystem and in the

RxRPC networking subsystem when processing paged fragments. A local

attacker could use this to escalate privileges, or possibly escape a

container. (CVE-2026-43284, CVE-2026-43500)

It was discovered that a logic flaw existed in the XFRM ESP-in-TCP

subsystem in the Linux kernel when handling socket buffer fragments. This

flaw is known as Fragnesia. A local attacker...

Update Instructions

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

Ubuntu 22.04 LTS
  linux-image-5.15.0-1074-xilinx-zynqmp  5.15.0-1074.78
  linux-image-xilinx-zynqmp       5.15.0.1074.77
  linux-image-xilinx-zynqmp-5.15  5.15.0.1074.77

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.
