Unspecified vulnerability in the EXT4_IOC_MOVE_EXT (aka move extents) ioctl implementation in the ext4 filesystem in the Linux kernel 2.6.32-git6 and earlier allows local users to cause a denial of service (filesystem corruption) via unknown vectors, a different vulnerability than CVE-2009-4131.

Upstream could not reproduce the issue, and so do not have a fix for this :/
