CVE-2026-64316 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() and gen_split_key() to avoid leaking secrets at runtime when CONFIG_DYNAMIC_DEBUG is enabled.
A vulnerability in the Linux kernel's CAAM crypto module allows sensitive key material to be leaked at runtime when dynamic debugging is enabled. This issue arises because the module improperly handles key dumps in certain functions, creating a risk of exposing secret information.
Users can apply the latest patches from the Linux kernel stable tree, which address this vulnerability by modifying the CAAM crypto module to use a safer function for dumping key material.
