AV:N and UI:R match a crafted page, but AC:H reflects the probabilistic race and the real prerequisite of a pre-compromised renderer; S:C with C/I/A:H captures the full sandbox escape into the browser process.
vuln.today treats the vendor’s rating as authoritative. A higher third-party CVSS (e.g. CISA-ADP) is shown for transparency but does not drive the headline severity.

Race in USB in Google Chrome prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Sandbox escape in Google Chrome desktop prior to 150.0.7871.47 lets an attacker who has already compromised the renderer process break out of the sandbox by winning a race condition in the USB subsystem via a crafted HTML page. Chromium rated it Medium severity despite the 9.6 CVSS, reflecting that it is a second-stage bug requiring prior renderer compromise; there is no public exploit identified at time of analysis and it is not in CISA KEV, with EPSS at just 0.21% (11th percentile).
Technical ContextAI
The flaw is a CWE-362 race condition (concurrent execution using shared resource with improper synchronization) inside Chromium's USB (WebUSB/device) implementation, which straddles the boundary between the sandboxed renderer and the more-privileged browser process. Chrome's multi-process security model confines web content to a locked-down renderer; the USB broker code in the browser process handles privileged device operations. A time-of-check/time-of-use style race in this inter-process pathway can be manipulated so that a compromised renderer corrupts state in the browser process, undermining the sandbox boundary. The CPE cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:* confirms the affected product is the Chrome application across versions below the fix.
RemediationAI
Vendor-released patch: update Google Chrome to 150.0.7871.47 or later on all desktop platforms; Chrome typically auto-updates, so ensure the browser has been fully relaunched to apply the update and confirm the version under chrome://settings/help. Reference the vendor advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. Because exploitation requires a compromised renderer plus WebUSB interaction, interim compensating controls include disabling WebUSB via enterprise policy (the DefaultWebUsbGuardSetting / WebUsbBlockedForUrls group policies) to remove the vulnerable device pathway - trade-off: this breaks legitimate web-based USB device workflows - and enforcing prompt update deployment via managed Chrome policy. Users of Chromium-based browsers should apply the equivalent update from their respective vendors.
