See How to fix? for RHEL:7 relevant fixed versions and status.
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_le to make it clear that we are referring to a little endian formatted data structure. And, update the routine with proper le32_to_cpu macro usages.
