CVE-2009-2692: Buffer Overflow

First published: Wed Aug 12 2009(Updated: )

Description of problem: Reported by Tavis Ormandy and Julien Tinnes. The SOCKOPS_WRAP macro from include/linux/net.h doesn't initialise the sendpage operation in the proto_ops structure correctly. Leading to a kernel NULL pointer dereference, and thus a local privilege escalation. Acknowledgements: Red Hat would like to thank Tavis Ormandy and Julien Tinnes of the Google Security Team for responsibly reporting this flaw.
