CVE-2013-3301: Linux Kernel

High severity, CVSS 7.2. EPSS: 1% chance of exploitation in the next 30 days.

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.
