Remote crafted page needs only user visit (PR:N/UI:R), but reliable heap-overflow sandbox escape requires exploit sophistication so AC:H; scope changes (S:C) on escape with full host impact.
vuln.today treats the vendor’s rating as authoritative. A higher third-party CVSS (e.g. CISA-ADP) is shown for transparency but does not drive the headline severity.

Heap buffer overflow in Dawn in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Sandbox escape in Google Chrome's Dawn WebGPU implementation (versions prior to 151.0.7922.72) lets a remote attacker corrupt heap memory in the GPU process via a crafted HTML page, potentially breaking out of the renderer sandbox to compromise the host. The CVSS 3.1 vector (AV:N/UI:R/S:C, base 9.6) reflects that exploitation only needs a victim to visit a malicious site but crosses a security boundary; Google rates the Chromium severity as Medium. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to load an attacker-controlled HTML page in a vulnerable Chrome (prior to 151.0.7922.72) with WebGPU/Dawn enabled - WebGPU is enabled by default on supported platforms and GPUs, so most default desktop installs are exposed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals conflict and should be weighed together. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious web page containing crafted WebGPU/JavaScript that drives Dawn into an out-of-bounds heap write, then lures a victim into visiting it (link, ad, or compromised site). Given UI:R and low attack complexity, a single page load in a vulnerable Chrome could corrupt GPU-process memory and, if chained successfully, escape the sandbox to run code on the host. … |
| Remediation | Vendor-released patch: update Google Chrome to 151.0.7922.72 or later on the Stable channel, which contains the Dawn fix; verify via chrome://settings/help and relaunch to complete the update, as Chrome staged rollouts can delay automatic delivery. … Detailed patch versions, workarounds, and compensating controls in full report. |
