AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Remote crafted page with no auth but required user interaction (UI:R); high C/I/A from code execution, S:U because impact stays within the renderer sandbox.

Use after free in WebRTC in Google Chrome prior to 147.0.7727.138 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Sandboxed remote code execution in Google Chrome's WebRTC component affects all desktop builds prior to 147.0.7727.138, where a crafted HTML page triggers a use-after-free (CWE-416) that lets a remote attacker run arbitrary code within the renderer sandbox. Google rates the Chromium severity as High and has shipped a fix in the Stable channel; there is no public exploit identified at time of analysis and the EPSS probability is negligible (0.01%). Exploitation requires the victim to visit an attacker-controlled page (UI:R), and code execution is confined to the sandbox unless chained with a separate sandbox-escape bug.
Technical ContextAI
The flaw lives in WebRTC, the real-time communication stack Chromium uses for peer-to-peer audio, video, and data channels; because WebRTC processes untrusted media/session data automatically when a page instantiates an RTCPeerConnection or related APIs, it is a recurring source of memory-safety bugs. The root cause is CWE-416 (Use After Free): an object is freed while a dangling reference to it remains reachable, and subsequent access to that freed memory allows an attacker who controls heap layout to redirect execution or corrupt state. The affected CPE is cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:* (all versions below the fixed build). Chromium's multi-process architecture means WebRTC runs in the sandboxed renderer, so the initial impact is contained to that low-privilege process rather than the host OS.
RemediationAI
Vendor-released patch: update Google Chrome to 147.0.7727.138 or later via the Stable channel; installations that use Chrome's automatic updater will receive it on next restart, so verify by relaunching and checking chrome://settings/help. See the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/04/stable-channel-update-for-desktop_28.html and VulDB entry https://vuldb.com/vuln/360069. Downstream Chromium rebuilds should apply the equivalent Red Hat/SUSE distribution updates. If patching cannot be completed immediately, a targeted compensating control is to disable or restrict WebRTC - for example via enterprise policy (WebRtcAllowLegacyTLSProtocols/URL-based restrictions) or by blocking untrusted sites from using RTCPeerConnection - which reduces the attack surface but breaks legitimate video-conferencing and voice features; combined with restricting general web browsing to trusted destinations, this narrows exposure until the update is deployed.
