Use after free in Bluetooth 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: Medium)
AnalysisAI
Sandbox-escaping remote code execution affects Google Chrome on macOS before 152.0.7977.65 through a use-after-free in the browser's Bluetooth component (CVE-2026-79091). A remote attacker who lures a victim into opening a crafted HTML page can trigger the freed-memory reuse to run arbitrary code outside the renderer sandbox, giving control of the host process. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to be running Google Chrome on macOS at a version below 152.0.7977.65 and to be socially engineered into opening an attacker-controlled crafted HTML page (CVSS UI:R confirms required user interaction). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals conflict and should be weighed carefully. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious HTML page that abuses Chrome's Bluetooth handling and, using phishing or a lure link, convinces a macOS user to open it in a vulnerable Chrome build. Loading the page triggers the use-after-free, and the attacker reuses the freed memory to execute arbitrary code that breaks out of the renderer sandbox into the browser process. … |
| Remediation | Vendor-released patch: update Google Chrome to 152.0.7977.65 or later on macOS via the Stable channel (restart the browser to apply, as Chrome staged updates only take effect after relaunch); see the Chrome release advisory at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html and issue https://issues.chromium.org/issues/523557855. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all macOS systems running Chrome versions prior to 152.0.7977.65 and mandate immediate updates; notify users that this addresses a critical remote code execution flaw. …
