Use after free in Bluetooth in Google Chrome on Mac prior to 149.0.7827.103 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Heap corruption in Google Chrome on macOS prior to version 149.0.7827.103 can be triggered remotely through a crafted HTML page that exploits a use-after-free condition in the browser's Bluetooth component. Successful exploitation requires the victim to visit attacker-controlled content but no authentication, and Google has rated the underlying Chromium severity as High with no public exploit identified at time of analysis.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to be running Google Chrome on macOS at a version prior to 149.0.7827.103 and to load attacker-controlled HTML/JavaScript in that browser (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 score reflects network attack vector, low complexity, no privileges required, and high impact across confidentiality, integrity, and availability - but UI:R (user interaction required) means the victim must visit a malicious page, which tempers drive-by-style mass exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A remote attacker hosts a crafted HTML page containing JavaScript that invokes Web Bluetooth APIs in a sequence that frees an internal Bluetooth-related object and then reuses the dangling reference with attacker-shaped heap content. A macOS user running a vulnerable Chrome build is lured to the page via phishing, malvertising, or a watering-hole compromise, triggering heap corruption that the attacker grooms into arbitrary code execution inside the renderer, typically as the first stage of a chain that pairs with a sandbox escape for full device compromise. … |
| Remediation | Apply the vendor-released patch by upgrading Google Chrome on macOS to version 149.0.7827.103 or later via the Stable channel update documented at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0153744567.html; restart the browser after update to ensure the patched binary is loaded. … Detailed patch versions, workarounds, and compensating controls in full report. |
