DescriptionCVE.org

Use after free in Chromoting in Google Chrome on Linux prior to 149.0.7827.53 allowed a remote attacker to execute arbitrary code via malicious network traffic. (Chromium security severity: Low)

AnalysisAI

Remote code execution in Google Chrome on Linux versions prior to 149.0.7827.53 allows a remote attacker to exploit a use-after-free condition in the Chromoting component via malicious network traffic. The flaw carries a CVSS 3.1 score of 8.1 (high) with no public exploit identified at time of analysis and an EPSS probability of 0.04%, though Google rates the Chromium severity as Low. The vendor has shipped a fix in the stable channel update for desktop.

Technical ContextAI

Chromoting is the underlying remote-desktop technology behind Chrome Remote Desktop, allowing one Chrome/Chromium instance to access another machine over the network. The root cause is CWE-416 (Use After Free), a class of memory-corruption bug where freed heap memory is later dereferenced; in browser components processing untrusted network input, such dangling pointers can be groomed to redirect control flow and achieve arbitrary code execution within the affected process. The affected product is the Linux build of Google Chrome at versions earlier than 149.0.7827.53, with the vulnerable code path reachable through the Chromoting remoting protocol handling.

RemediationAI

Vendor-released patch: Google Chrome 149.0.7827.53 (Linux) - upgrade to this version or later via the stable channel, as announced at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html. On managed Linux fleets, push the updated Chrome package through your distribution's package manager or enterprise update channel and restart the browser to load the patched binary. As an interim compensating control on hosts that cannot be patched immediately, disable or uninstall the Chrome Remote Desktop host/extension to remove the Chromoting attack surface (trade-off: users lose remote-desktop functionality), and restrict inbound network paths used by Chromoting at the host firewall to trusted peers only. Additional issue tracking is at https://issues.chromium.org/issues/502461760.
