CVE-2026-7353 is a heap buffer overflow vulnerability in the Skia graphics library used by Google Chrome before version 147.0.7727.138. An attacker who has compromised the renderer process could exploit this flaw via a crafted HTML page to perform a sandbox escape, potentially gaining higher privileges or executing arbitrary code outside the sandbox. The vulnerability has a CVSS v3.1 score of 8.3, indicating high severity with network attack vector, high impact on confidentiality, integrity, and availability, and requiring user interaction.

Successful exploitation could allow an attacker with control over the renderer process to escape the Chrome sandbox, potentially leading to arbitrary code execution with elevated privileges. This compromises the browser's security isolation mechanisms, increasing risk to the host system's confidentiality, integrity, and availability. There are no reports of active exploitation in the wild.

A fix is available in Google Chrome version 147.0.7727.138 and later. Users and administrators should update to this version or newer to remediate the vulnerability. The vendor advisory linked (https://chromereleases.googleblog.com/2026/04/stable-channel-update-for-desktop_28.html) provides official update details. No additional mitigations are specified by the vendor.
