Integer overflow or wraparound in Microsoft Edge (Chromium-based) allows an unauthorized attacker to execute code over a network.
AnalysisAI
Remote code execution in Microsoft Edge (Chromium-based) allows an unauthenticated attacker to run arbitrary code by luring a victim to a malicious web page that triggers an integer overflow (CWE-190). The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R) indicates network-based exploitation requiring user interaction, with high confidentiality, integrity, and availability impact. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively open or render attacker-controlled web content in Microsoft Edge (Chromium-based) - the CVSS UI:R metric confirms user interaction is mandatory, so this cannot be triggered purely remotely without a user action. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals point to a genuinely high-priority browser flaw but not an emergency. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious web page (or delivers it via a link in phishing email, a compromised ad, or a watering-hole site) containing content crafted to trigger the integer overflow in Edge's rendering engine. When the victim opens the page, the overflow corrupts memory in the renderer and executes attacker-controlled code with the browser's privileges. … |
| Remediation | Patch available per vendor advisory: update Microsoft Edge to the fixed build published by Microsoft, consulting the MSRC advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-57974 for the exact patched version number, which is not stated in the available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify all systems running Microsoft Edge through asset inventory tools and alert all users to avoid clicking suspicious links or visiting untrusted websites. …
