Background
The IB/qib package is a part of the Linux Kernel ecosystem and is responsible for providing InfiniBand (IB) support for the QLogic InfiniPath adapter. It enables high-speed communication between servers and devices in a cluster. The package includes the struct qib_user_sdma_pkt, which is used for managing data transfers between user space and the InfiniBand hardware. However, a buffer overflow vulnerability has been discovered in the fields of this structure.
Vulnerability Detail
The buffer overflow vulnerability in the struct qib_user_sdma_pkt fields allows an attacker to overwrite adjacent memory locations, potentially leading to arbitrary code execution or system crashes. This vulnerability was introduced in version v2.6.35 of the Linux Kernel and has been fixed in version v4.4.292. The impact and attack plausibility of this vulnerability have not been proven yet.
