Doc Text:
A flaw was found in the Linux kernel's Cryptographic Acceleration and Assurance Module (CAAM) driver. This vulnerability allows for the leakage of sensitive cryptographic key material. When the kernel's dynamic debugging feature is enabled, an attacker could potentially exploit improper handling of key dumps in cryptographic setup functions, leading to the disclosure of confidential information.

Description OSIDB Bzimport 2026-07-25 10:07:14 UTC 
In the Linux kernel, the following vulnerability has been resolved:

crypto: caam - use print_hex_dump_devel to guard key hex dumps

Use print_hex_dump_devel() for dumping sensitive key material in
*_setkey() to avoid leaking secrets at runtime when CONFIG_DYNAMIC_DEBUG
is enabled.
