Vendor: Qualcomm

Description

The vulnerability allows a local application to escalate privileges on the system.

The vulnerability exists due to a boundary condition in the WLAN Host component when calculating length of WMI messages. A local application can send an overly long WMI message to trigger an out-of-bounds read error and execute arbitrary code with elevated privileges.

Mitigation
Install updates from vendor's website.
