DescriptionCVE.org

Inappropriate implementation in GPU in Google Chrome on Android prior to 149.0.7827.53 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

Sandbox escape in Google Chrome on Android prior to 149.0.7827.53 allows a remote attacker who has already compromised the renderer process to break out of the sandbox via a crafted HTML page that abuses an inappropriate implementation in the GPU component. The flaw requires user interaction (visiting a malicious page) and presupposes a prior renderer compromise, but a successful chain yields full sandbox escape on the mobile platform. No public exploit identified at time of analysis, and EPSS exploitation probability is very low (0.05%, 15th percentile).

Technical ContextAI

The vulnerable component is the GPU process in Chromium on Android, which mediates accelerated graphics operations between renderer processes and the underlying device drivers. CWE-20 (Improper Input Validation) here reflects that the GPU implementation does not adequately validate input received from the renderer, enabling a compromised renderer to influence GPU process behavior in unintended ways. Because Chrome's security model treats the GPU process as a higher-privilege boundary relative to renderers, flaws in this IPC-facing validation are a classic stepping stone for sandbox escape chains on Android, where the renderer is normally confined by SELinux and seccomp policies. Affected builds are Chrome for Android before 149.0.7827.53.

RemediationAI

Upgrade Google Chrome on Android to version 149.0.7827.53 or later via the Google Play Store or managed-device update channels; the vendor-released patch is documented in the Chrome Releases stable-channel announcement at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html and tracked in https://issues.chromium.org/issues/501461853. There is no documented configuration-level workaround inside Chrome itself, but because exploitation requires first compromising the renderer via a malicious page, interim compensating controls include enforcing enterprise policies that restrict browsing to allowlisted sites, deploying mobile threat defense / EDR on Android fleets to detect anomalous Chrome child-process behavior, and using MDM to enforce minimum Chrome versions - accepting the trade-off that allowlisting breaks general browsing and MDM enforcement requires managed devices.
