This vulnerability involves a use-after-free condition in the WebShare feature of Google Chrome on Android before version 149.0.7827.53. An attacker with control over the renderer process could exploit this to perform a sandbox escape, which could lead to elevated privileges or further compromise of the device. The issue is recognized by Chromium security with a medium severity rating. No CVSS score is assigned, and the vendor advisory does not explicitly confirm patch availability in the provided information.

If exploited, this vulnerability could allow an attacker who has already compromised the renderer process to escape the sandbox environment, potentially leading to greater control over the device or execution of arbitrary code outside the browser sandbox. However, there are no known exploits in the wild at this time, and the impact is limited to affected versions of Chrome on Android prior to 149.0.7827.53.

Patch status is not yet confirmed — check the vendor advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html for current remediation guidance. Users should update Google Chrome on Android to version 149.0.7827.53 or later once available. Until then, no additional specific mitigations are provided by the vendor.
