Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2016-8636. PoCs published by jigerjain.

AI-analyzed exploit summary This repository contains a functional proof-of-concept for CVE-2016-8636, demonstrating an integer overflow vulnerability in the `mem_check_range` function. The code replicates the flawed logic that allows an overflow when calculating `iova + length`, leading to incorrect bounds checking.

Description

Integer overflow in the mem_check_range function in drivers/infiniband/sw/rxe/rxe_mr.c in the Linux kernel before 4.9.10 allows local users to cause a denial of service (memory corruption), obtain sensitive information from kernel memory, or possibly have unspecified other impact via a write or read request involving the "RDMA protocol over infiniband" (aka Soft RoCE) technology.
