NVD Description
Note: Versions mentioned in the description apply only to the upstream libvirt-daemon-config-network package and not the libvirt-daemon-config-network package as distributed by AlmaLinux.
See How to fix? for AlmaLinux:9 relevant fixed versions and status.
A flaw was found in libvirt. A refactor of the code fetching the list of interfaces for multiple APIs introduced a corner case on platforms where allocating 0 bytes of memory results in a NULL pointer. This corner case would lead to a NULL-pointer dereference and subsequent crash of virtinterfaced. This issue could allow clients connecting to the read-only socket to crash the virtinterfaced daemon.
