Microsoft SRV2.SYS SMB2 Logoff Remote Kernel NULL Pointer Dereference
This module triggers a NULL pointer dereference in the SRV2.SYS kernel driver when processing an SMB2 logoff request before a session has been correctly negotiated, resulting in a BSOD. Effecting Vista SP1/SP2 (And possibly Server 2008 SP1/SP2), the flaw was resolved with MS09-050.
