Description

In the Linux kernel, the following vulnerability has been resolved: scsi: qedf: Fix NULL dereference in error handling Smatch reported: drivers/scsi/qedf/qedf_main.c:3056 qedf_alloc_global_queues() warn: missing unwind goto? At this point in the function, nothing has been allocated so we can return directly. In particular the "qedf->global_queues" have not been allocated so calling qedf_free_global_queues() will lead to a NULL dereference when we check if (!gl[i]) and "gl" is NULL.
