CVE-2010-4649

Published: 18 February 2011

Integer overflow in the ib_uverbs_poll_cq function in drivers/infiniband/core/uverbs_cmd.c in the Linux kernel before 2.6.37 allows local users to cause a denial of service (memory corruption) or possibly have unspecified other impact via a large value of a certain structure member.

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.
