CVE-2026-11177

chromium-browser: Use after free in Omnibox

Published Jun 4, 2026 CVSS 3.1 · 8.8 High EPSS < 1% KEV · Not listed

Description

Use after free in Omnibox in Google Chrome prior to 149.0.7827.53 allowed a remote attacker who convinced a user to engage in specific UI gestures to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Medium)

Analysis

Technical impact

The vulnerability is a use-after-free flaw in the Omnibox component of Google Chrome that can lead to heap corruption when a specially crafted HTML page is viewed and the user performs certain UI gestures. If the heap is corrupted, an attacker could potentially execute arbitrary code or cause a denial of service. This weakness is classified as both CWE-416 (Use After Free) and CWE-825 (Heap Corruption).

Affected Systems

Google Chrome versions prior to 149.0.7827.53 on the stable channel are affected. The issue applies to all platforms that ship the impacted browser release; no other products or vendors are listed.

Risk and Exploitability

The CVSS score is 8.8, indicating high severity. The EPSS score is < 1%, suggesting a low likelihood of exploitation. The vulnerability is not listed in the CISA KEV catalog. Based on the description, it is inferred that the likely attack vector involves a remote attacker delivering a malicious web page that forces a user to engage in specific UI interactions with the Omnibox. The user must visit the page while running the affected Chrome version; the exploit requires user interaction but could lead to arbitrary code execution if the heap corruption is successfully triggered.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Upgrade Google Chrome to version 149.0.7827.53 or later via the browser’s built-in update mechanism.
If a patch cannot be applied immediately, consider disabling address-bar autocomplete features via enterprise policy to reduce the attack surface as a temporary measure.
Avoid interacting with untrusted web pages that may target the Omnibox; use safe browsing tools or web filters to block malicious content.
