In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Ensure DAID handling completion before deleting an NPIV instance Deleting an NPIV instance requires all fabric ndlps to be released before an NPIV's resources can be torn down. Failure to release fabric ndlps beforehand opens kref imbalance race conditions. Fix by forcing the DAID to complete synchronously with usage of wait_queue.
