CVE-2011-1044

Published: 18 February 2011

The ib_uverbs_poll_cq function in drivers/infiniband/core/uverbs_cmd.c in the Linux kernel before 2.6.37 does not initialize a certain response buffer, which allows local users to obtain potentially sensitive information from kernel memory via vectors that cause this buffer to be only partially filled, a different vulnerability than CVE-2010-4649.

From the Ubuntu security team

Dan Carpenter discovered that the Infiniband driver did not correctly handle certain requests. A local user could exploit this to crash the system or potentially gain root privileges.
