Description Zvonko Kosic 2021-06-16 11:53:30 UTC

In RHEL 8, when a kernel module is loaded, the kernel checks the signature of the module against the public X.509 keys from the kernel system keyring (.builtin_trusted_keys) and the kernel platform keyring (.platform). The .platform keyring contains keys from third-party platform providers and custom public keys. The keys from the kernel system .blacklist keyring are excluded from verification.

Additional tools are: yum -y install openssl mokutil keyutils
