Software vendor:
Qualcomm

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

The vulnerability exists due to a type conversion error in LTE within the Modem component, caused by incorrectly decoding hex data for the SIB2 OTA message and assigning a garbage value to choice when processing the SRS configuration. A remote attacker can pass specially crafted data to the system, trigger a type conversion error and perform a denial of service (DoS) attack.
