Severity by source
AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
Requires a prior renderer compromise (PR:H) and chaining a second bug plus a heap grooming primitive (AC:H); once achieved the sandbox escape changes scope with full impact.
Primary rating from Vendor (Chrome).

Use after free in ANGLE in Google Chrome prior to 151.0.7922.72 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's ANGLE graphics layer (versions prior to 151.0.7922.72) lets a remote attacker who has already compromised the renderer process break out of the browser sandbox via a crafted HTML page. Rated Chromium severity High with a CVSS 9.6, the flaw is a use-after-free (CWE-416) reported by Google's own Chrome team; a vendor patch is available. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker has ALREADY compromised Chrome's renderer process - this is a sandbox-escape/second-stage bug, not a standalone unauthenticated entry point, despite the PR:N in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The published CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H) yields 9.6, driven by network vector, scope change (sandbox escape), and full CHIA impact - but this rating is in tension with the description, which explicitly requires an attacker to have ALREADY compromised the renderer process. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker first compromises Chrome's renderer via a separate flaw (e.g., a V8 or DOM bug), then serves a crafted HTML page that drives malicious WebGL/GPU calls into ANGLE to trigger the use-after-free and pivot out of the sandbox into higher-privileged browser context. Because AV:N/AC:L applies once the renderer stage is achieved, the escape itself is low-complexity, but no public exploit code has been identified at time of analysis. |
| Remediation | Vendor-released patch: update Google Chrome to 151.0.7922.72 or later, per the Chrome Stable channel update (https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html); Chrome's auto-update will apply this on relaunch, so ensure users fully restart the browser to load the new binary. … Detailed patch versions, workarounds, and compensating controls in full report. |
