Remote crafted page needs the user to open it (UI:R) but no auth (PR:N); sandbox escape crosses a trust boundary (S:C) with full C/I/A impact.

Use after free in Skia in Google Chrome prior to 150.0.7871.46 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Critical)
AnalysisAI
Sandbox escape in Google Chrome's Skia graphics library affects all desktop Chrome builds prior to 150.0.7871.46, where a use-after-free (CWE-416) triggered by a crafted HTML page can let a remote attacker break out of the renderer sandbox. Google rates the Chromium severity Critical and CVSS is 9.6, but there is no public exploit identified at time of analysis and CISA's SSVC records exploitation status as none. A vendor patch is available in the June 2026 Stable channel release.
Technical ContextAI
The flaw resides in Skia, Chromium's 2D graphics rendering engine used to rasterize web content, canvas, and compositing operations. As a CWE-416 use-after-free, the root cause is that Skia continues to reference a heap object after it has been freed, allowing a specially crafted HTML page to reclaim and control that memory. Because Skia runs across renderer and GPU processes, corrupting its object lifetime is a well-known primitive for escalating from renderer-level code execution toward a sandbox escape. The affected CPE is cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:* covering all versions below the fixed build.
RemediationAI
Vendor-released patch: update Google Chrome to 150.0.7871.46 or later via the June 2026 Stable channel update (https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html), then fully restart the browser so all renderer and GPU processes reload the patched Skia code. In managed fleets, force the update through enterprise update policies rather than relying on user-initiated relaunch. As an interim compensating control before patching, restrict browsing to trusted sites and keep Chrome's site isolation and sandbox enabled; note these reduce but do not eliminate exposure since the trigger is a crafted HTML page, so patching remains the only reliable fix.
