Use after free in Bluetooth in Google Chrome on Mac prior to 149.0.7827.103 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Critical)
AnalysisAI
Sandbox escape in Google Chrome on macOS prior to 149.0.7827.103 allows a remote attacker who has already compromised the renderer process to break out of the browser sandbox via a use-after-free flaw in the Bluetooth component, triggered by a crafted HTML page. Chromium rates the severity as Critical, and a vendor patch is available; no public exploit has been identified at time of analysis, though the bug is tracked in the Chromium issue tracker (516987814).
Technical ContextAI
The vulnerability resides in Chrome's Bluetooth implementation, which exposes the Web Bluetooth API to renderer processes and brokers privileged operations through higher-privilege browser-process code on macOS. The root cause is CWE-416 (Use-After-Free): an object backing a Bluetooth operation is freed while a dangling reference remains reachable, allowing the attacker to reclaim the freed memory with controlled data and hijack subsequent operations. Because Bluetooth IPC crosses the renderer/browser-process boundary on macOS, corrupting state here lets an already-compromised renderer escape the Chrome sandbox into the more privileged browser process context.
RemediationAI
Vendor-released patch: Google Chrome 149.0.7827.103 for macOS - upgrade immediately via Chrome's built-in updater or by redeploying the managed package, then ensure end users restart the browser so the update actually takes effect (Chrome staying open indefinitely is a common reason patches don't land). The Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0153744567.html is the authoritative source. If patching cannot happen immediately, a targeted compensating control is to disable the Web Bluetooth API via the DefaultWebBluetoothGuardSetting enterprise policy set to 2 (block), which removes the attack surface for this specific bug at the cost of breaking any internal web apps that rely on Web Bluetooth; site isolation should also be confirmed enabled (it is by default) to raise the cost of the prerequisite renderer compromise. Users of Chromium-based browsers should monitor their respective vendor advisories for the merged upstream fix.
