CWEhttps://cwe.mitre.org/data/definitions/134.html

Format string vulnerability in the register_disk function in block/genhd.c in the Linux kernel through 3.9.4 allows local users to gain privileges by leveraging root access and writing format string specifiers to /sys/module/md_mod/parameters/new_array in order to create a crafted /dev/md device name.

Weakness

The product uses a function that accepts a format string as an argument, but the format string originates from an external source.
