DESCRIPTION:
A weakness has been reported in the Linux Kernel, which can be
exploited by malicious people to cause a DoS (Denial of Service).

The weakness is caused due to a race condition within the InfiniBand
request handling, which can be exploited to cause a kernel crash.

Do not use InfiniBand to interconnect with untrusted systems.
