The ext4_fill_flex_info function in fs/ext4/super.c in the Linux
kernel before 2.6.32-git6 allows user-assisted remote attackers to
cause a denial of service (divide-by-zero error and panic) via a
malformed ext4 filesystem containing a super block with a large
FLEX_BG group size (aka s_log_groups_per_flex value).
