Software vendor:
Qualcomm

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in Data Modem when processing DSM packets. A remote unauthenticated attacker can send specially crafted DSM packets to the system, trigger a stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
