CVE-2024-53110

Service interruption via unterminated device ID array

Published Dec 2, 2024 · Updated Aug 5, 2026

Improper null termination in the Linux vp_vdpa driver allows local users to interrupt service by triggering undefined-memory access. The vp_vdpa probe allocates a one-element virtio_device_id array without the null terminator that vdpa_mgmtdev_get_classes() expects, so iteration proceeds beyond the allocation. A local low-privileged user must reach the affected vDPA management path; the resulting service interruption is not publicly characterized as a crash or hang.
