Description OSIDB Bzimport 2024-08-30 13:15:59 UTC 
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` if virConnectListInterfaces() is called requesting 0 networks to be filled.

The bug was introduced in libvirt-10.4.0 and reproduces only on platforms where allocation of 0-length memory returns NULL instead of a valid pointer.
