|Description||The ext4_fill_super function in fs/ext4/super.c in the Linux kernel 2.6.27 before 22.214.171.124 and 2.6.28 before 126.96.36.199 does not validate the superblock configuration, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) by attempting to mount a crafted ext4 filesystem.|

The information below is based on the following data on fixed versions.

Since the feature is experimental until 2.6.27, I don't think we need to fix this
