(CVE-2025-21703, CVE-2024-53237, CVE-2024-50256, CVE-2024-56651,
CVE-2024-46826, CVE-2025-21700, CVE-2021-47119, CVE-2024-26915,
CVE-2025-21702, CVE-2024-49974, CVE-2024-35958)

Update instructions:

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

Ubuntu 20.04 LTS
  linux-image-5.4.0-1062-xilinx-zynqmp  5.4.0-1062.66
  linux-image-xilinx-zynqmp       5.4.0.1062.62

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.
