Vulnerability Details CVE-2021-47039
In the Linux kernel, the following vulnerability has been resolved:
ataflop: potential out of bounds in do_format()
The function uses "type" as an array index:
q = unit[drive].disk[type]->queue;
Unfortunately the bounds check on "type" isn't done until later in the
function. Fix this by moving the bounds check to the start.
