Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ataflop: potential out of bounds in do_format()<br /> <br /> The function uses "type" as an array index:<br /> <br /> q = unit[drive].disk[type]-&gt;queue;<br /> <br /> Unfortunately the bounds check on "type" isn&amp;#39;t done until later in the<br /> function. Fix this by moving the bounds check to the start.
