chromium-browser: Out of bounds read in WebRTC

Published Jun 4, 2026 CVSS 3.1 · 6.5 Medium EPSS < 1% KEV · Not listed

Description

Out of bounds read in WebRTC in Google Chrome prior to 149.0.7827.53 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: Medium)

Analysis

Technical impact

The vulnerability is an out‑of‑bounds read in WebRTC on Google Chrome versions prior to 149.0.7827.53. A malicious web page can trigger the bug and allow a remote attacker to read arbitrary data from the browser’s process memory. The consequence is potentially sensitive information disclosure, identified as CWE-125.

Affected Systems

The affected product is Google Chrome built on the Chromium engine. Any desktop installation of Chrome before version 149.0.7827.53 is vulnerable, unless the user has already applied the update released in the June 2026 stable channel.

Risk and Exploitability

The advisory lists a CVSS score of 6.5 and an EPSS score of less than 1%, indicating a moderate likelihood of exploitation. The vulnerability is not listed in the KEV catalog, and the attack vector is remote through a crafted HTML page that triggers the out‑of‑bounds read. Until the patch is applied, an attacker who can host a malicious page accessed by the victim can leak process memory contents.

Affected Products

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