kernel/trace/ftrace.c in the Linux kernel before 220.127.116.11, when
debugfs is enabled, does not properly handle interaction between mutex
possession and llseek operations, which allows local users to cause a
denial of service (NULL pointer dereference and outage of all function
tracing files) via an lseek call on a file descriptor associated with
the set_ftrace_filter file.
