Background
The RDMA/hfi1 package is a component of the Linux Kernel that provides support for high-performance networking using Remote Direct Memory Access (RDMA) technology. RDMA allows for efficient data transfer between networked devices by bypassing the operating system's network stack. The hfi1 driver specifically supports Mellanox InfiniBand Host Channel Adapters (HCAs). This vulnerability in RDMA/hfi1 involves potential integer multiplication overflow errors.
Vulnerability Detail
The vulnerability arises from potential integer multiplication overflow errors in the RDMA/hfi1 package. If an attacker can trigger these errors, it may lead to various security issues, including denial of service (DoS) attacks or potential privilege escalation. The vulnerability was introduced in version v4.3 of the Linux Kernel and was fixed in version v4.9.318. The impact and attack plausibility of this vulnerability have not been proven yet.
