Vendor: Qualcomm

Description

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

The vulnerability exists due to a boundary error when processing SSID length received from beacon or probe response during an IBSS session. A remote attacker can send specially crafted traffic to the device, trigger memory corruption and execute arbitrary code on the target system.

Mitigation
Install updates from vendor's website.
