(CVE-2024-53051, CVE-2024-46787, CVE-2024-50047, CVE-2024-56662,
CVE-2025-37890, CVE-2025-38001, CVE-2025-37997, CVE-2025-37932,
CVE-2025-37798, CVE-2025-38177, CVE-2025-38000)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 20.04 LTS
linux-image-5.4.0-1052-iot 5.4.0-1052.55
Available with Ubuntu Pro
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.
