CVE-2010-3904

Published: 19 October 2010

The rds_page_copy_user function in net/rds/page.c in the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel before 2.6.36 does not properly validate addresses obtained from user space, which allows local users to gain privileges via crafted use of the sendmsg and recvmsg system calls.

From the Ubuntu Security Team

Dan Rosenberg discovered that the RDS network protocol did not correctly check certain parameters. A local attacker could exploit this gain root privileges.
