Impact is a reliable kernel crash/DoS (and theoretically harder-to-exploit memory corruption) when a device is removed while the work is pending. This can be reproduced by hot-unplug/PCI reset or module removal on systems using the mvsas HBA while its delayed work is active. For the CVSS the PR:H, because requires local access and a specific hardware/driver configuration, typically with admin-level ability to trigger device removal.", "threat_severity": "Moderate"}
