DescriptionCVE.org

Use after free in Codecs in Google Chrome on Windows prior to 149.0.7827.103 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)

AnalysisAI

Sandbox escape in Google Chrome on Windows before 149.0.7827.103 allows a remote attacker who has already compromised the renderer process to break out of the browser sandbox via a use-after-free in the Codecs component triggered by a crafted HTML page. Google rates this Chromium security severity as High, and a vendor patch is available; no public exploit was identified at time of analysis, though the scope-changed CVSS 8.3 reflects the cross-boundary impact of breaching the sandbox.

Technical ContextAI

The flaw resides in the Codecs subsystem of Chromium's media stack, which decodes audio/video content within the renderer process. CWE-416 (Use After Free) means memory is freed while a dangling pointer remains reachable, allowing an attacker to influence the freed allocation and corrupt control or data structures when the pointer is dereferenced. In Chrome's multi-process architecture, the renderer is normally confined by the OS sandbox; a UAF reachable in higher-privileged code paths invoked from a compromised renderer can be chained to cross the sandbox boundary on Windows, where this issue is specifically scoped per the advisory.

RemediationAI

Vendor-released patch: Chrome 149.0.7827.103 for Windows - upgrade immediately via the Chrome Releases stable channel update at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0153744567.html, and validate enterprise rollout through Google Update / managed deployment channels. For managed fleets, force a relaunch policy so the new build is actually loaded rather than sitting staged. Until patched endpoints are confirmed, compensating controls include enforcing Site Isolation (default but verify via chrome://flags and policy), disabling unnecessary media codecs is not generally configurable in Chrome so it is not a practical workaround, and restricting browsing to trusted destinations via SafeBrowsing Enhanced Protection plus a web proxy/DNS filter to reduce the chance of users loading attacker-controlled HTML; note these only reduce exposure and do not eliminate the underlying UAF. Downstream Chromium-based browsers (Edge, Brave, Opera, Electron apps) should be tracked separately for their respective backports.
