Subject: [PATCH] qcacld-2.0: Add lost AP sample size entry to nla policy
|
||
|
|
|
||
|
|
Incorrect validation of
|
||
|
|
QCA_WLAN_VENDOR_ATTR_EXTSCAN_BSSID_HOTLIST_PARAMS_LOST_AP_SAMPLE_SIZE
|
||
|
|
results in assigning an unchecked user-controller value.
|
||
|
|
This can lead to buffer overflow.
|
||
|
|
|
||
|
|
validate
|
||
|
|
QCA_WLAN_VENDOR_ATTR_EXTSCAN_BSSID_HOTLIST_PARAMS_LOST_AP_SAMPLE_SIZE.
