Subject: ASoC: msm8x16-wcd: prevent out of bounds access
|
||
|
|
||
|
Hardcoding the third argument in strnstr function
|
||
|
is resulting in out of bounds access. Set the third argument
|
||
|
to sizeof the character string passed as the first argument
|
||
|
to prevent out of bounds access.
|
||
|
|
||
