Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
uaccess: fix integer overflow on access_ok()<br />
<br />
Three architectures check the end of a user access against the<br />
address limit without taking a possible overflow into account.<br />
Passing a negative length or another overflow in here returns<br />
success when it should not.<br />
<br />
Use the most common correct implementation here, which optimizes<br />
for a constant &#39;size&#39; argument, and turns the common case into a<br />
single comparison.
