(CVE-2025-37890, CVE-2024-46787, CVE-2025-37798, CVE-2025-38000,
CVE-2025-37932, CVE-2025-38001, CVE-2025-37997, CVE-2024-50047,
CVE-2024-53051)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 22.04 LTS
linux-image-5.15.0-1080-intel-iot-realtime 5.15.0-1080.82
Available with Ubuntu Pro
linux-image-intel-iot-realtime 5.15.0.1080.84
Available with Ubuntu Pro
linux-image-intel-iot-realtime-5.15 5.15.0.1080.84
Available with Ubuntu Pro
Ubuntu 20.04 LTS
linux-image-5.15.0-1087-aws 5.15.0-1087.94~20.04.1
Available with Ubuntu Pro
linux-image-aws 5.15.0.1087.94~20.04.1
Available with Ubuntu Pro
linux-image-aws-5.15 5.15.0.1087.94~20.04.1
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.
