Subject: qcacld-2.0: Validate "set passpoint list" network count
|
|
|
|
Currently when processing the "set passpoint list" vendor command the
|
|
"number of networks" parameter is not limit checked. This value is
|
|
subsequently used to calculate the size of a buffer. Add a limit check
|
|
to ensure that an appropriately sized buffer is always allocated.
