ulp/sdp/sdp_proc.c in the ib_sdp module (aka ib_sdp.ko) in the ofa_kernel package in the InfiniBand driver implementation in OpenFabrics Enterprise Distribution (OFED) before 1.5.3 does not properly handle certain non-array variables, which allows local users to cause a denial of service (stack memory corruption and system crash) by reading the /proc/net/sdpstats file.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
