CVE-2026-64315 Details
Description
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.
A vulnerability in the Linux kernel's CAAM crypto module has been addressed. The issue involved improper handling of sensitive key material during key management operations, which could lead to unintentional key leakage at runtime. This vulnerability was particularly relevant when the dynamic debug feature was enabled, potentially exposing secrets to unauthorized access.
The vulnerability has been fixed in the Linux kernel. Users should upgrade to the latest version of the stable Linux kernel where this issue has been addressed.
