C887V and Cisco IOS and IOS XE Software IKEv1 1 Fragmentation Denial of Service Vulnerability CSCuy47382

According to Cisco IOS Software Checker i have to install 15.1(4)M12a. But the latest version available is 15.1(4)M10. Does Cisco provide a fix for this critical bug (CSCuy47382) or not?

Best regards,

Benjamin
