Use after free in Safebrowsing in Google Chrome on on Mac prior to 152.0.7977.65 allowed a remote attacker leveraging social engineering to execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: Critical)
AnalysisAI
Remote code execution in Google Chrome on macOS (versions prior to 152.0.7977.65) stems from a use-after-free in the Safe Browsing component that lets a remote attacker escape the renderer sandbox and run arbitrary code on the host. Exploitation requires luring a victim to a crafted HTML page (social engineering / user interaction), and Chromium rates the flaw Critical. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to visit or render an attacker-crafted HTML page in Google Chrome on macOS prior to 152.0.7977.65 - i.e., mandatory user interaction (UI:R) driven by social engineering, per the description. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are mixed and should be weighed together rather than in isolation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker sets up a crafted HTML page and uses phishing or a malicious ad/link to lure a macOS Chrome user to it; when the page loads, it triggers the Safe Browsing use-after-free, corrupts heap memory, and escapes the sandbox to execute attacker code with the user's privileges. No credentials are needed, but the victim must open the page (UI:R). … |
| Remediation | Vendor-released patch: update Google Chrome to 152.0.7977.65 or later on macOS via the Stable channel update described at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html, then fully relaunch the browser so the new binary is loaded (Chrome auto-updates but a restart is required to apply). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, confirm Chrome auto-update is enabled organization-wide and communicate the critical patch (Chrome 152.0.7977.65) to all macOS users. …
