## Overview

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

crypto: starfive - Correctly handle return of sg_nents_for_len

The return value of sg_nents_for_len was assigned to an unsigned long
in starfive_hash_digest, causing negative error codes to be converted
to large positive integers.

Add error checking for sg_nents_for_len and return immediately on
failure to prevent potential buffer overflows.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
