Technical details
The vulnerability exists in the CompareTelUris function of SipAddress.cpp in the Android Framework's telephony component, where an incorrect bounds check allows an out-of-range array access. This triggers an unhandled exception that crashes the telephony process, resulting in denial of service. The attack requires network access but no user interaction or elevated privileges.
