kernel: infiniband: Unprivileged process can overwrite kernel memory using rdma_ucm.ko
The InfiniBand (aka IB) stack in the Linux kernel before 4.5.3 incorrectly relies on the write system call, which allows local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a uAPI interface.
A flaw was found in the way certain interfaces of the Linux kernel's Infiniband subsystem used write() as bi-directional ioctl() replacement, which could lead to insufficient memory security checks when being invoked using the splice() system call. A local unprivileged user on a system with either Infiniband hardware present or RDMA Userspace Connection Manager Access module explicitly loaded, could use this flaw to escalate their privileges on the

CVE-2016-4565 kernel: infiniband: Unprivileged process can overwrite kernel memory using rdma_ucm.ko
It was reported that drivers/infiniband stack uses write() as a replacement for bi-directional ioctl(), which is not safe. There are ways to trigger write calls that result in the return structure that is normally written to user space being shunted off to user specified kernel memory instead.
A local unprivileged user on a system with rdma_ucm module loaded could use this flaw to escalate their privileges.
