Ubuntu Security Notice USN-7928-4
December 19, 2025
linux-raspi vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-raspi: Linux kernel for Raspberry Pi systems
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:
- Cryptographic API;
- Media drivers;
- Network drivers;
- AFS file system;
- F2FS file system;
- Tracing infrastructure;
- Netfilter;
(CVE-2022-49390, CVE-2024-47691, CVE-2024-50067, CVE-2024-53090,
CVE-2024-53218, CVE-2025-21855, CVE-2025-39964, CVE-2025-39993,
CVE-2025-40018)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 22.04 LTS
linux-image-5.15.0-1092-raspi 5.15.0-1092.95
linux-image-raspi 5.15.0.1092.90
linux-image-raspi-5.15 5.15.0.1092.90
linux-image-raspi-nolpae 5.15.0.1092.90
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.
