|Description||The ext4_fill_super function in fs/ext4/super.c in the Linux kernel 2.6.27 before 126.96.36.199 and 2.6.28 before 188.8.131.52 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.|
|Source||CVE (at NVD; LWN, oss-sec, fulldisc, bugtraq, EDB, Metasploit, Red Hat, Ubuntu, Gentoo, SuSE, Mageia, GitHub code/issues, web search, more)|
|NVD severity||medium (attack range: local)|
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
