CVE-2016-7194: Microsoft Edge Chakra engine memory corruption allows remote code execution

Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 19 September 2026. Confidence: medium.

high priorityRemote code execution in a widely deployed browser with a high EPSS score, though exploitation requires user interaction and no KEV listing or public exploit tag is present.

What it is

The Chakra JavaScript engine in Microsoft Edge contains a memory corruption flaw (CWE-119) that a crafted web site can trigger. Successful exploitation allows arbitrary code execution or a denial of service in the browser process. It is a distinct issue from CVE-2016-3386, CVE-2016-3389 and CVE-2016-7190.

Impact

An attacker can execute arbitrary code in the context of the Edge renderer or crash it, giving code execution on the victim's machine or a denial of service.

Attack surface

Reached over the network by a victim visiting a malicious or compromised web page; no authentication is required but user interaction (browsing to the page) is needed per the CVSS vector AV:N/UI:R.

Exploitation

Not listed in CISA KEV and no reference is tagged as exploit code, but EPSS is 0.579 (99th percentile), indicating elevated predicted exploitation activity.

What to do

• Apply Microsoft security bulletin MS16-119 (October 2016) or later cumulative Edge/Windows updates.
• Keep Edge and the underlying Windows platform fully patched; this engine flaw is fixed only through vendor updates.
• Enforce browsing isolation or an alternate hardened browser for untrusted web content where Edge cannot be updated.
• Block or filter known malicious sites and untrusted script delivery at the network/proxy layer.
• Reduce exposure by disabling or restricting JavaScript-heavy content in Edge for high-risk user groups.

Detection

• Monitor Edge/Chakra crash reports and Windows Error Reporting events for repeated renderer memory-corruption crashes.
• Hunt for suspicious child processes spawned by Edge (browser or renderer) that indicate post-exploitation code execution.
• Review proxy and DNS logs for access to newly registered or low-reputation sites delivering exploit pages.
• Correlate endpoint telemetry for anomalous memory allocation or shellcode-like behavior in Edge processes.
