# CVE-2024-8235: Libvirt: crash of virtinterfaced via virconnectlistinterfaces()

Status: published. Published: 2024-08-30. Updated: 2026-11-05.

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.
