Use after free in Chromoting in Google Chrome prior to 152.0.7977.65 allowed a remote attacker to potentially execute arbitrary code outside the sandbox via crafted network traffic. (Chromium security severity: Medium)
AnalysisAI
Use-after-free in Chrome's Chromoting (remote desktop) component allows a remote, unauthenticated attacker to potentially execute arbitrary code outside the browser sandbox via crafted network traffic, affecting all Chrome versions prior to 152.0.7977.65. The sandbox-escape dimension elevates this beyond a typical renderer vulnerability, as successful exploitation could yield code execution in a broader process context. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the targeted Chrome instance is actively running the Chromoting component - meaning the user has Chrome Remote Desktop configured and a Chromoting session is established or being negotiated, making this not a default-configuration exposure for typical browser users. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H) reflects network-reachable exploitation requiring no credentials and no user interaction, but with high attack complexity - consistent with SSVC's 'Automatable: no' determination. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who can send crafted network traffic to a Chrome instance actively using the Chromoting (Chrome Remote Desktop) protocol triggers a use-after-free condition in the Chromoting network handler. By carefully controlling heap memory layout - requiring the high attack complexity captured in AC:H - the attacker redirects execution to attacker-controlled data, achieving arbitrary code execution outside Chrome's sandbox. … |
| Remediation | Update Google Chrome to version 152.0.7977.65 or later, which contains the vendor-released patch as confirmed by the Chrome stable channel update advisory at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Start within 24 hours by inventorying Chrome versions in your environment (navigate to chrome://settings/help on test endpoints) and immediately disabling Chromoting via Chrome policies if not business-critical, or restricting access to internal networks only. …
