Severity by source
AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Network-delivered crafted page (AV:N/AC:L/PR:N) requires the victim to open it (UI:R); code runs within the renderer sandbox so scope stays Unchanged with high C/I/A.

Use after free in Loader in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Remote code execution in Google Chrome's Loader component before 151.0.7922.72 allows a remote attacker to execute arbitrary code inside the browser's renderer sandbox by luring a victim to a crafted HTML page (CWE-416 use-after-free). The flaw carries a High Chromium severity and CVSS 8.8, but code execution is confined to the sandbox and requires user interaction (visiting the page); a full-system compromise would need an additional sandbox-escape bug. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively load attacker-controlled web content - the CVSS UI:R and the description's 'crafted HTML page' confirm user interaction (navigating to or rendering a malicious/compromised page, including via an iframe or ad) is mandatory; there is no unauthenticated drive-by without page load. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H = 8.8) reflects a network-reachable, low-complexity, unauthenticated bug that nonetheless requires user interaction (UI:R) - a victim must open a malicious page. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page (or injects it via a malvertising slot or compromised site) that triggers the use-after-free in Chrome's Loader; when a victim running a pre-151.0.7922.72 build visits the page, the freed-memory reuse corrupts heap state and yields arbitrary code execution within the renderer sandbox. To achieve host compromise the attacker would chain this with a separate sandbox-escape vulnerability. … |
| Remediation | Vendor-released patch: upgrade Google Chrome to 151.0.7922.72 or later on the Stable channel; Chrome typically auto-updates, so confirm via chrome://settings/help and relaunch to apply, and use enterprise policies (e.g., forced auto-update, minimum-version enforcement) to guarantee fleet-wide rollout. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Chrome deployments across the organization and confirm current version status; flag any devices running versions before 151.0.7922.72 for priority patching. …
