Subject: [PATCH] qcacld-2.0: Avoid integer overflow in
|
|
wma_enable_arp_ns_offload
|
|
|
|
In the function wma_enable_arp_ns_offload(), the len variable is
|
|
defined as signed 32 bit, whereas wmi_buf_alloc() takes unsigned
|
|
16 bit as input also there is no limit on input of
|
|
num_ns_offload_count.
|
|
|
|
Fix is to define the len variable in wma_enable_arp_ns_offload()
|
|
as unsigned 32 bit. The length input for wmi_buf_alloc() is also
|
|
extended and re-defined as unsigned 32 bit. Add limit check before
|
|
using num_ns_offload_count.
|
