Subject: msm: ipc: Possible memory corruption due to Sign Conversion
|
||
|
|
|
||
|
|
msm_ipc_router_skb_to_buf() takes an unsigned argument and assigns the
|
||
|
|
same to a signed local variable. This might cause issues when the value
|
||
|
|
of the argument is too high.
|
||
|
|
|
||
|
|
Change the datatype of the local variable to unsigned.
