CVE-2024-50183

System interruption via asynchronous DA_ID completion

Published Nov 8, 2024 · Updated May 11, 2026

Race condition in affected Linux kernel lpfc releases allows local users to interrupt the system during privileged NPIV deletion. The lpfc NPIV-deletion path tears down vport resources before asynchronous DA_ID processing releases every fabric node, creating a kref imbalance race. Exploitation requires privileged NPIV management on lpfc Fibre Channel hardware; the primary published assessment limits impact to availability.
