CVE-2026-9117 is a high-severity type confusion vulnerability in the GFX component of Google Chrome affecting Linux and ChromeOS builds prior to version 148.0.7778.179. The flaw occurs in graphics-processing functionality associated with video handling, where a crafted video file can trigger access to a resource using an incompatible type. According to the available information, exploitation requires that the attacker has already compromised the renderer process and then uses the GFX flaw as a second-stage primitive to cross Chrome's sandbox boundary. The issue is specific to Linux and ChromeOS implementations of the affected component and is not reported to affect Windows or macOS.
