Integer overflow in Skia in Google Chrome prior to 148.0.7778.216 allowed a remote attacker who had compromised the renderer process to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Sandboxed arbitrary code execution in Google Chrome versions prior to 148.0.7778.216 stems from an integer overflow in the Skia graphics library, allowing a remote attacker who has already compromised the renderer process to execute code within the sandbox via a crafted HTML page. Chromium rates this High severity, and no public exploit has been identified at time of analysis, though the vulnerability is part of a multi-stage exploit chain where renderer compromise is a prerequisite. The CVSS 7.5 score reflects high attack complexity (AC:H) and required user interaction (UI:R), making mass exploitation less likely than the impact metrics alone would suggest.
Technical ContextAI
Skia is the open-source 2D graphics library used by Chrome (and other Chromium-derived browsers) to render geometry, text, and images across HTML canvas, CSS, and WebGL surfaces. CWE-472 (External Control of Assumed-Immutable Web Parameter) is the assigned weakness class, though the description points more directly to an integer overflow in Skia's rendering math - overflow conditions in graphics pipelines typically arise from unchecked arithmetic on dimensions, offsets, or buffer sizes derived from attacker-influenced HTML/CSS input, which can corrupt subsequent allocations or bounds checks. Affected CPE is cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*, scoped to versions before 148.0.7778.216. Because the attacker must already control the renderer process, the bug functions as a sandbox-internal primitive (e.g., chained with a separate renderer RCE) rather than a standalone entry point.
RemediationAI
Vendor-released patch: Google Chrome 148.0.7778.216 - update via the built-in Chrome update mechanism or push the new stable channel via enterprise management (Chrome Browser Cloud Management, GPO, Jamf, Intune). Reference the Stable Channel update at https://chromereleases.googleblog.com/2026/05/stable-channel-update-for-desktop_0877304591.html and the Chromium issue tracker at https://issues.chromium.org/issues/513973560 for confirmation. Chromium-derived browsers should be updated as soon as their respective vendors release builds incorporating the fixed Skia commit. As a compensating control until patching, enforce Site Isolation (enabled by default in modern Chrome) and restrict execution of untrusted web content via enterprise policies such as URLBlocklist or sandboxed VDI browsing; disabling hardware-accelerated graphics is not an effective workaround since Skia is used regardless of GPU acceleration and disabling it would degrade rendering performance without removing the vulnerable code path.
