CVE-2016-8636
Description
From CVE.org
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.
Statement
This issue did not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux as they did not include the software implementation of the RDMA protocol over infiniband.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
