Description

A NULL pointer dereference was found in the QLogic qedf FCoE driver. In the error handling path of qedf_alloc_global_queues(), calling qedf_free_global_queues() when nothing was allocated causes a crash.

Statement

This affects systems with QLogic FCoE adapters. The crash occurs only on allocation failure error paths during driver initialization, which requires memory pressure or other resource constraints.
