Ubuntu Security Notice USN-7701-3
August 21, 2025
linux-iot vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-iot: Linux kernel for IoT platforms
Details:
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
- Device tree and open firmware driver;
- SCSI subsystem;
- TTY drivers;
- SMB network file system;
- Bluetooth subsystem;
- Network traffic control;
(CVE-2023-52975, CVE-2024-38541, CVE-2025-37797, CVE-2024-49950,
CVE-2024-50073, CVE-2023-52757, CVE-2025-38083)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 20.04 LTS
linux-image-5.4.0-1053-iot 5.4.0-1053.56
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.
