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).
