Published Jan 5, 2026

Overview

CVE-2025-68763 is a known-severity vulnerability. It was published on January 5, 2026.

Technical Description

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

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
