In the Linux kernel, the following vulnerability has been resolved:

scsi: lpfc: Revise lpfc_prep_embed_io routine with proper endian macro usages

On big endian architectures, it is possible to run into a memory out of
bounds pointer dereference when FCP targets are zoned.

In lpfc_prep_embed_io, the memcpy(ptr, fcp_cmnd, sgl->sge_len) is
referencing a little endian formatted sgl->sge_len value.  So, the memcpy
can cause big endian systems to crash.

Redefine the *sgl ptr as a struct sli4_sge_l
