CVE-2013-2851
First published: Fri May 31 2013(Updated: )
A flaw was found in the way certain disk names were interpreted by the Linux kernel. Block layer uses the "disk_name" field as a format string in a number of places. While this is normally not a problem due to how disk names are created (statically or incrementally), there is currently at least one way to define nearly arbitrary names via md. A privileged (uid 0) local user could potentially use this flaw to execute code at ring0. Acknowledgements: Red Hat would like to thank Kees Cook for reporting this issue.
