Answer in brief
CVE-2023-5090 records a Medium severity (CVSS 6.0) vulnerability in Kernel: kvm: svm: improper check in svm_set_x2apic_msr_interception allows direct access to host x2apic msrs. The current sources do not mark it as known exploited. Affected software not mapped in the current feed; confirm the named product and version against your inventory.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 6.0. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.
