Severity by source
AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H
Requires a pre-compromised renderer (PR:L) and reliable heap grooming plus user interaction (AC:H, UI:R); sandbox escape crosses a trust boundary (S:C) with full host impact.
Primary rating from Vendor (Chrome).

Use after free in Skia 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: Critical)
AnalysisAI
Sandbox escape in Google Chrome's Skia graphics library (versions prior to 151.0.7922.72) allows a remote attacker who has already compromised the renderer process to break out of the sandbox and gain broader access on the host via a crafted HTML page. Google rates the Chromium severity as Critical, and CVSS is 8.3 due to the scope change (S:C) reflecting the sandbox boundary crossing. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker has ALREADY compromised the Chrome renderer process - this is a second-stage sandbox-escape primitive, not a standalone entry point. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS vector CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H yields 8.3 (High), driven largely by the scope change (S:C) and full CIA impact, but tempered by high attack complexity (AC:H) and required user interaction (UI:R). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker first compromises Chrome's renderer process using a separate vulnerability (for example, a V8 or DOM bug) delivered via a malicious web page. From within that already-compromised renderer, the attacker serves crafted HTML that triggers the use-after-free in Skia, reclaims the freed memory, and uses the resulting corruption to escape the sandbox into a higher-privilege browser process. … |
| Remediation | Vendor-released patch: Google Chrome 151.0.7922.72. … Detailed patch versions, workarounds, and compensating controls in full report. |
