GoKawiilAndroid bug lets a single SMS crash phone app and drop calls
Researcher Mark Blaszczyk disclosed a flaw in Android's telephony stack where a malformed WAP Push SMS causes an unchecked integer cast to produce a negative array size, triggering an uncaught exception that kills the com.android.phone process. The crash requires no interaction from the recipient and can terminate active calls, including emergency calls. Google classified the report as non-security and marked it won't fix, so no CVE was issued despite the 90-day disclosure window elapsing.
