Upgrade AlmaLinux:9 libvirt-nss to version 0:8.5.0-7.el9_1 or higher.
This issue was patched in ALSA-2022:8003.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libvirt-nss package and not the libvirt-nss package as distributed by AlmaLinux.
See How to fix? for AlmaLinux:9 relevant fixed versions and status.
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).
