(CVE-2021-47188, CVE-2024-39494, CVE-2022-48791, CVE-2022-48863,
CVE-2024-42228, CVE-2024-38570, CVE-2024-42160, CVE-2024-26787,
CVE-2024-27012, CVE-2024-26677)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 18.04 LTS
linux-image-5.4.0-1117-raspi 5.4.0-1117.129~18.04.1
Available with Ubuntu Pro
linux-image-raspi-hwe-18.04 5.4.0.1117.129~18.04.1
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.
