Software vendor:
Qualcomm

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper validation of DNS response when DNS client requests with PTR, NAPTR or SRV query type within the Data Modem component. A remote attacker can send a specially crafted response to the device, trigger an assertion failure and perform a denial denial of service (DoS) attack.
