CVE-2013-3301

Published: 29 April 2013

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.

From the Ubuntu security team

A flaw was discovered in the Linux kernel's ftrace subsystem interface. A local user could exploit this flaw to cause a denial of service (system crash).
