Detailsinfo

A vulnerability classified as problematic has been found in Linux Kernel up to 3.8.8 (Operating System). Affected is the function set_ftrace_pid/set_graph_function of the component CAP_SYS_ADMIN. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. CVE summarizes:

The ftrace implementation in the Linux kernel before 3.8.8 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by leveraging the CAP_SYS_ADMIN capability for write access to the (1) set_ftrace_pid or (2) set_graph_function file, and then making an lseek system call.

The weakness was presented 04/12/2013 by Prasad J Pandit with Red Hat Security Response Team as not defined mailinglist post (Maillist). The advisory is shared for download at openwall.com. This vulnerability is traded as CVE-2013-3301 since 04/28/2013. The exploitability is told to be easy. The attack needs to be approached locally. The exploitation doesn't require any form of authentication. Technical details and a public exploit are known.
