    CVE-2022-0897

    Summary: libvirt security update

    Details: Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). The main package includes the libvirtd server exporting the virtualization support. Security Fix(es): A flaw was found in the libvirt nwfilter driver. The virNWFilterObjListNumOfNWFilters method failed to acquire the `driver->nwfilters` mutex before iterating over virNWFilterObj instances. There was no protection to stop another thread from concurrently modifying the `driver->nwfilters` object. This flaw allows a malicious, unprivileged user to exploit this issue via libvirt’s API virConnectNumOfNWFilters to crash the network filter management daemon (libvirtd/virtnwfilterd).(CVE-2022-0897)
