CVE-2024-1441

Daemon crash via off-by-one interface-name write

Published Mar 11, 2024 · Updated Nov 8, 2025

Off-by-one error in libvirt 9.7.0 allows local users to crash the libvirt daemon through crafted interface-list API requests. udevListInterfacesByStatus() accepts count equal to names_len and writes one additional interface name, including a null-pointer dereference for a zero-length null array. Unprivileged local client access is sufficient; the demonstrated consequence is interruption of virtualization management, not privilege gain or code execution.
