The __scm_destroy function in net/core/scm.c in the Linux kernel
2.6.27.4, 2.6.26, and earlier makes indirect recursive calls to itself
through calls to the fput function, which allows local users to cause
a denial of service (panic) via vectors related to sending an
SCM_RIGHTS message through a UNIX domain socket and closing file
descriptors.
