AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
Remote unauthenticated network traffic (AV:N/PR:N/UI:N) but a use-after-free race gives AC:H; total system compromise yields C:H/I:H/A:H with unchanged scope.

Use after free in Chromoting in Google Chrome on ChromeOS prior to 150.0.7871.47 allowed a remote attacker to execute arbitrary code via malicious network traffic. (Chromium security severity: Critical)
AnalysisAI
Remote code execution in Google Chrome on ChromeOS (versions prior to 150.0.7871.47) stems from a use-after-free in the Chromoting (Chrome Remote Desktop) component, letting a remote attacker corrupt memory and execute arbitrary code through malicious network traffic. Google rates the Chromium severity as Critical, and CVSS scores it 8.1 with a high attack complexity. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the Chromoting (Chrome Remote Desktop) code path be reachable and processing attacker-supplied network traffic on a ChromeOS device running a version prior to 150.0.7871.47; the attacker needs a network path to that remoting traffic but needs no credentials (PR:N) and no user interaction (UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals here are mixed and point to a serious-but-not-imminent priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A remote attacker who can reach a ChromeOS device's Chromoting/remote-desktop session sends specially crafted network traffic that triggers the use-after-free, reclaiming freed memory with controlled data to gain code execution in the affected process. The AV:N/AC:H profile means no authentication or user interaction is needed, but the attacker must win a timing/lifetime race, and no public POC is currently available. |
| Remediation | Vendor-released patch: 150.0.7871.47 - update Chrome/ChromeOS to 150.0.7871.47 or later per the Google Stable channel advisory (https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html); on managed ChromeOS fleets, confirm auto-update is enabled and force a device restart so the new version applies. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all Chrome and ChromeOS systems running versions prior to 150.0.7871.47; alert teams responsible for Chrome/ChromeOS fleet management. …
