CVE-2024-50184

System hang via unchecked virtio-pmem device status

Published Nov 8, 2024 · Updated May 11, 2026

Denial of service in affected Linux releases allows local users to hang the system through a bad-status virtio-pmem device. virtio_pmem_flush() sends a flush request without first confirming that the device is activated, then waits indefinitely for a host acknowledgment when the device status is bad. Local low-privileged access and a configured virtio persistent-memory device are required; the observed consequence is a system hang.
