Linux NULL pointer dereference due to incorrect proto_ops initializations
Aug 14, 2009, 12:03 (1 Talkback[s])
"The issue lies in how Linux deals with unavailable operations
for some protocols. sock_sendpage and others don't check for NULL
pointers before dereferencing operations in the ops structure.
Instead the kernel relies on correct initialization of those
proto_ops structures with stubs (such as sock_no_sendpage) instead
of NULL pointers."
