8.8

CVSS v3.1

Official Description

In Open vSwitch (OvS) 2.5.0, a malformed IP packet can cause the switch to read past the end of the packet buffer due to an unsigned integer underflow in `lib/flow.c` in the function `miniflow_extract`, permitting remote bypass of the access control list enforced by the switch.

Technical Analysis

CVE-2016-10377 requires adjacent network access, limiting remote exploitation but still posing risk in shared or local network environments.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.

From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
