CRITICAL 9.6

DescriptionCVE.org

Insufficient policy enforcement in GPU in Google Chrome prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Low)

AnalysisAI

Sandbox escape in Google Chrome's GPU process before 150.0.7871.47 lets a remote attacker who has already compromised the renderer process break out of the sandbox via a crafted HTML page. The flaw is a protection-mechanism failure (CWE-693) that Google patched in the June 2026 Stable channel update; Chromium rated its intrinsic severity Low because it is only useful as the second link in an exploit chain, and no public exploit has been identified at time of analysis. EPSS probability is low (0.17%, 7th percentile), consistent with a chained bug rather than a mass-exploitable entry point.

Technical ContextAI

The vulnerability lives in Chrome's GPU process, which handles hardware-accelerated graphics (WebGL, WebGPU, compositing) and is a privileged component the renderer talks to over Chromium's Mojo IPC. Chrome's multi-process security model confines web content to a low-privilege, sandboxed renderer; the GPU process enforces policy on the commands and resources the renderer may request. CWE-693 (Protection Mechanism Failure) here means that policy enforcement in the GPU is insufficient, so a renderer that has been subverted can issue requests the sandbox boundary was supposed to reject, escalating out of the renderer sandbox. This is not a memory-corruption primitive by itself but a logic/enforcement gap that becomes valuable when combined with a prior renderer compromise (e.g., a V8 or DOM bug).

RemediationAI

Vendor-released patch: update Google Chrome to 150.0.7871.47 or later on all desktop platforms, per Google's Stable channel advisory (https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html); Chrome normally auto-updates, so ensure the browser has been fully relaunched to apply the update and confirm the version via chrome://settings/help. There is no supported configuration workaround for the enforcement gap itself, but because exploitation requires a prior renderer compromise, defense-in-depth reduces exposure: enabling the Site Isolation and strict sandbox defaults (do not launch Chrome with --no-sandbox or --disable-gpu-sandbox, which would remove the boundary this bug targets), and in managed fleets disabling unnecessary hardware acceleration/WebGPU where GPU features are not needed can shrink the attack surface at the cost of graphics performance. Managed environments should push the update via enterprise policy rather than relying solely on per-user auto-update.
