CVSS 3.1
7.1 highCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:HCVE-2021-47039
High (7.1) in linux linux kernel. EPSS 0.2% chance of exploitation in the next 30 days.
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.
