Ubuntu.comUB:CVE-2021-47039CVE-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.
