Insufficient validation of untrusted input in Dawn in Google Chrome on Linux and ChromeOS prior to 149.0.7827.103 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Sandbox escape in Google Chrome and ChromeOS on Linux prior to 149.0.7827.103 allows a remote attacker who has already compromised the renderer process to break out of the browser sandbox via a crafted HTML page abusing the Dawn (WebGPU) component. Chromium rates the severity High, and while no public exploit identified at time of analysis, sandbox-escape bugs in Dawn are historically chained with renderer RCE bugs in exploit chains. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Two stacked prerequisites: (1) the attacker must have already achieved code execution inside a Chrome renderer process - typically via a separate, chained renderer RCE - because Dawn IPC is only reachable from a compromised renderer, not directly from JavaScript on a normal page; (2) the victim must visit attacker-controlled HTML in Chrome or ChromeOS on Linux at a version below 149.0.7827.103, satisfying the UI:R user-interaction requirement. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS vector AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H paints a nuanced picture: network-reachable and unauthenticated, but with High attack complexity and required user interaction (visiting a malicious page), tempered by a Scope-changed full-impact outcome. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A targeted user is lured to a crafted webpage that first triggers a separate renderer-process vulnerability to gain code execution inside the sandboxed renderer, then issues malformed WebGPU/Dawn commands across the IPC boundary to corrupt state in the GPU process and escape the sandbox. The attacker thereby gains code execution in a higher-privilege Chrome process on Linux or ChromeOS, enabling persistent access, credential theft, or further OS-level escalation. … |
| Remediation | Vendor-released patch: Chrome 149.0.7827.103 on Linux and the corresponding ChromeOS stable-channel build - upgrade immediately per the Chrome Releases advisory (https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0153744567.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
