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.
