CWE ID 125

Summary

CVE-2021-47039 is a vulnerability affecting the Linux kernel that has been addressed. The issue lies in the 'ataflop' function within the 'do_format()' process. The function makes use of the 'type' variable as an array index, but the bounds check on 'type' is carried out later in the function, leading to potential out-of-bounds access. This vulnerability could result in unintended kernel behavior or system crashes. The vulnerability has been mitigated by moving the bounds check for 'type' to the beginning of the function.
