NULL Pointer Dereference

Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
scsi: lpfc: Revise lpfc_prep_embed_io routine with proper endian macro usages<br />
<br />
On big endian architectures, it is possible to run into a memory out of<br />
bounds pointer dereference when FCP targets are zoned.<br />
<br />
In lpfc_prep_embed_io, the memcpy(ptr, fcp_cmnd, sgl->sge_len) is<br />
referencing a little endian formatted sgl->sge_len value. So, the memcpy<br />
can cause big endian systems to crash.<br />
<br />
Redefine the *sgl ptr as a struct sli4_sge_le to make it clear that we are<br />
referring to a little endian formatted data structure. And, update the<br />
routine with proper le32_to_cpu macro usages.
