Sign kernel modules with SHA-512
Medium Severity
This configures the kernel to build and sign modules using SHA512 as the hash function. The configuration that was used to build kernel is available at
/boot/config-*
. To check the configuration value for
CONFIG_MODULE_SIG_SHA512
, run the following command:
grep CONFIG_MODULE_SIG_SHA512 /boot/config-*
For each kernel installed, a line with value "y" should be returned.
