kvm svm

About this tag
The tag kvm svm covers Linux kernel vulnerabilities in KVM's SVM (Secure Virtual Machine) implementation, specifically in interrupt handling and System Management Mode (SMM) during SHUTDOWN interception. Discussions focus on CVE-2024-39483 and CVE-2025-37957, which affect Azure Linux and potentially other Microsoft artifacts. Topics include virtual NMI handling, NMI window requests, and SMM-related security flaws. The tag is relevant for IT professionals and security researchers tracking hypervisor-level vulnerabilities in Linux-based virtualization environments, particularly those using AMD processors with SVM support.
