Sorry for the terrible title. 36 new vulnerabilities were discovered, most of them denial of service it appears.
Why fix a vulnerability when other unfixable vulnerabilities of the same class exist?
The approach has merits and value, but the novelty here is doing a LTE fuzzer and finding implementation bugs IMHO. Which is very useful, but the title may lead people to believe there are new weaknesses in the standard itself. There are some standard level attacks, but it's local DoS and already known as far as I can see.
* Some of the DoS methods are bugs that could be triggered by normal equipment.
* Some of the DoS methods are easier to detect the source of. (i.e. it's a lot easier to detect and pinpoint a frequency jammer than a mobile phone sending invalid protocol messages)
