Description
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.
Affected configurations
• linux linux kernel (>= 5.11 < 5.11.21)
• linux linux kernel (>= 5.12 < 5.12.4)
