CVE-2024-8235

Daemon crash via zero-length interface list serialization

Published Aug 30, 2024 · Updated Nov 8, 2025

NULL-pointer dereference in libvirt 10.4.0 through 10.6.0 allows local users to crash virtinterfaced over its read-only socket. udevListInterfacesByStatus treats a zero-length names array as a request to count interfaces, causing RPC code to serialize a NULL list with a nonzero declared length. Any unprivileged client able to connect to the read-only socket can interrupt interface-management service without modifying configuration.
