Use after free in Aura in Google Chrome prior to 152.0.7977.65 allowed a remote attacker to execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: Critical)
AnalysisAI
Sandbox-escaping remote code execution in Google Chrome desktop before 152.0.7977.65 stems from a use-after-free in Aura, Chromium's UI/windowing framework. A remote attacker who lures a victim to a crafted HTML page can execute arbitrary code outside the browser sandbox, giving full control of the renderer host process. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to load attacker-controlled HTML in a vulnerable Chrome build (before 152.0.7977.65) - the CVSS UI:R confirms required user interaction, so a page visit or rendered content is mandatory; there is no drive-by-without-interaction path. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are mixed but lean toward high priority for a desktop browser. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious web page (or injects malicious content via a compromised ad or site) and entices a victim running a vulnerable Chrome build to open it. The page's crafted HTML/script triggers the use-after-free in Aura, corrupting browser-process memory to gain code execution outside the sandbox. … |
| Remediation | Vendor-released patch: update Google Chrome to 152.0.7977.65 or later on all desktop platforms via the Chrome Releases advisory (https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html); most installs auto-update, but force the update by opening chrome://settings/help and relaunching, and confirm managed/enterprise deployments have received it. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, initiate deployment of Google Chrome version 152.0.7977.65 or later across all managed endpoints using your standard software distribution mechanism. …
