Use after free in Chromoting in Google Chrome prior to 151.0.7922.173 allowed a remote attacker to execute arbitrary code outside the sandbox via crafted network traffic. (Chromium security severity: Critical)
AnalysisAI
Remote code execution outside the browser sandbox is possible in Google Chrome's Chromoting component (Chrome Remote Desktop protocol) prior to version 151.0.7922.173, exploitable by a remote attacker via crafted network traffic with user interaction. The root cause is a use-after-free (CWE-416) in Chromoting, enabling full compromise of confidentiality, integrity, and availability. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the victim is running Google Chrome prior to 151.0.7922.173 with the Chrome Remote Desktop (Chromoting) component active - either installed and running as a host, or in an active remote desktop session. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 8.8 (High/near-Critical) reflects network-reachable, unauthenticated (PR:N), low-complexity exploitation requiring only user interaction (UI:R), with full C/H/I/A impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who can reach a victim's machine over the network - for example, on a shared network or via the internet if Chromoting ports are exposed - sends specially crafted Chromoting protocol traffic to a Chrome instance where Chrome Remote Desktop is active. The malformed packets trigger a use-after-free in the Chromoting component, allowing the attacker to corrupt memory and redirect execution flow, ultimately running arbitrary code in a context outside the Chrome sandbox with the privileges of the browser process or host OS user. … |
| Remediation | Upgrade Google Chrome to version 151.0.7922.173 or later immediately; this is the vendor-released patch confirmed via the Chrome stable channel update advisory at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0404570826.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
