CWE-119Published: January 11, 2018· Updated: Jun 17, 2026
Official Description
Race condition in Jungo Windriver 12.5.1 allows local users to cause a denial of service (buffer overflow) or gain system privileges by flipping pool buffer size, aka a "double fetch" vulnerability.
Technical Analysis
CVE-2018-5189 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
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 7.8.
A proof-of-concept (PoC) exploit exists for CVE-2018-5189. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
