That would be an amazing result of CDU/CSU getting an absolute majority with 42.5% of the vote due to the 5% threshold. Reminds me of the Turkey election of 2002 where AKP won an absolute majority with 34% due to the 10% threshold.
Or the UK elections of 2005 where Labour won an absolute majority with 35%. 
Well, UK is FPTP so that is reasonable from a technical point of view. But Turkey just like Germany is a PR system so having results like this is out of the ordinary.
Scotland's relatively new system delivered an SNP majority with a 45% vote share. They even racked up a seat in a region where they won every single constituency seat. While mathematically possible of course it just took people by surprise.
