CVE-2023-2700

Es besteht eine Schwachstelle in libvirt. Der Speicher wird in "virPCIVirtualFunctionList" nicht richtig freigegeben. Ein Angreifer kann dies ausnutzen, um möglicherweise Informationen offenzulegen oder einen Denial of Service-Zustand herbeizuführen, indem er wiederholt die Fähigkeiten eines "SR-IOV PCI"-Geräts abfragt.
