Ubuntu 20.04: USN-7289-2 critical: kernel security issues

Several security issues were fixed in the Linux kernel.. ========================================================================== Ubuntu Security Notice USN-7289-2 February 25, 2025 linux-azure-5.15, linux-azure-fde-5.15, linux-oracle-5.15 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-azure-5.15: Linux kernel for Microsoft Azure cloud systems - linux-azure-fde-5.15: Linux kernel for Microsoft Azure CVM cloud systems - linux-oracle-5.15: Linux kernel for Oracle Cloud systems Details: Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

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.
