|Description||The ext4_isize function in fs/ext4/ext4.h in the Linux kernel 2.6.27 before 18.104.22.168 and 2.6.28 before 22.214.171.124 uses the i_size_high structure member during operations on arbitrary types of files, which allows local users to cause a denial of service (CPU consumption and error-message flood) by attempting to mount a crafted ext4 filesystem.|
|Source||CVE (at NVD; CERT, 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
