Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.2.2

Description The issue allows user-assisted remote attackers to trigger inconsistent filesystem-groups data and possibly cause a denial of service via a malformed ext4 filesystem containing a super block with a large FLEX BG group size (aka s log groups per flex value). This problem exists because of an incomplete fix for a previous issue.

Recommendations For Linux kernel versions prior to 3.2.2, update to version 3.2.2 or later to resolve the issue.
