CVE-2011-1044
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.
