Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the
lpfc prep embed io routine in the Linux kernel, where a memory out of bounds pointer dereference can occur on big endian architectures when FCP targets are zoned. This happens because the memcpy function references a little endian formatted sgl->sge len value, which can cause big endian systems to crash. The solution involves redefining the *sgl ptr as a struct sli4 sge le to clarify that it refers to a little endian formatted data structure and updating the routine with proper le32 to cpu macro usages.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
