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
Remote code execution in Google Chrome desktop before 152.0.7977.65 lets a remote attacker escape the renderer sandbox and run arbitrary code on the host after a victim opens a crafted HTML page. The flaw is a use-after-free in Aura, Chromium's UI/windowing layer, and Google rates its Chromium security severity as Critical (CVSS 9.6, scope-changed). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to open attacker-controlled web content in a vulnerable Chrome build (prior to 152.0.7977.65) - the CVSS UI:R and the description's 'crafted HTML page' make user interaction (visiting/rendering the page) a hard prerequisite; there is no drive-by-without-interaction path, which is also why SSVC marks Automatable:no. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are mostly consistent and point to a serious but not-yet-exploited flaw. … 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 malicious ad/compromised site) and lures a victim on an unpatched Chrome build to open it. The page triggers the Aura use-after-free, corrupts memory, and executes attacker code outside the renderer sandbox, giving control of the browser process on the host. … |
| Remediation | Vendor-released patch: 152.0.7977.65 - update Google Chrome to 152.0.7977.65 or later via the Chrome Releases stable-channel advisory (https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html), then fully restart the browser so the running process picks up the new build. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, prioritize Chrome updates to version 152.0.7977.65 or later for high-risk users including security personnel, developers, and executive staff. …
