## Overview

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

crypto: caam - guard HMAC key hex dumps in hash_digest_key

Use print_hex_dump_devel() for dumping sensitive HMAC key bytes in
hash_digest_key() to avoid leaking secrets at runtime when
CONFIG_DYNAMIC_DEBUG is enabled.

## Remediation

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