NVD Description

Note: Versions mentioned in the description apply only to the upstream libvirt-daemon-common package and not the libvirt-daemon-common package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

A NULL pointer dereference flaw was found in the udevConnectListAllInterfaces() function in libvirt. This issue can occur when detaching a host interface while at the same time collecting the list of interfaces via virConnectListAllInterfaces API. This flaw could be used to perform a denial of service attack by causing the libvirt daemon to crash.
