Description

A flaw was found in the Linux kernel's crypto: caam component. This vulnerability allows for the disclosure of sensitive HMAC (Hash-based Message Authentication Code) key bytes at runtime. The issue occurs because the hash_digest_key() function uses print_hex_dump_devel() without proper guarding, which can expose these keys when the CONFIG_DYNAMIC_DEBUG option is enabled. This information disclosure could potentially allow an attacker to gain unauthorized access to or tamper with data protected by these keys.
