Ubuntu 24.04 LTS linux-xilinx Critical Escalation Threats USN-8499-1

July 2, 2026

Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-xilinx: Linux kernel for Xilinx systems

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, CVE-2026-45998, CVE-2026-46000)

Update Instructions

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

Ubuntu 24.04 LTS
  linux-image-6.8.0-1032-xilinx   6.8.0-1032.33
  linux-image-xilinx              6.8.0.1032.33
  linux-image-xilinx-6.8          6.8.0.1032.33
  linux-image-xilinx-zynqmp       6.8.0.1032.33

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.
