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.
