Note that the DEBUG_SET_MODULE_RONX config option only depends on
CONFIG_MODULES being set, not on CONFIG_KERNEL_DEBUG, unlike in bug
1760643. So the Ubuntu Security Team would like to see
DEBUG_SET_MODULE_RONX enabled in the 4.4 linux-kvm kernel config. The
renamed config STRICT_MODULE_RWX is set for the 4.15 based linux-kvm
kernel in bionic.
Thanks.
