CVE-2024-8235: Libvirt: crash of virtinterfaced via virconnectlistinterfaces()
First published: Fri Aug 30 2024(Updated: )
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.
