Sandbox escape use-after-free in Graphite in Google Chrome
CVE-2026-6304 is a high-severity use-after-free vulnerability in the Graphite component of Google Chrome, specifically in Chrome’s Skia Graphite GPU rasterization backend. In affected versions prior to 147.0.7727.101, a freed object in the Graphite rasterization pipeline can be accessed after deallocation, creating a memory-safety flaw. Because Graphite operates in Chrome’s GPU process rather than the renderer process, successful exploitation can cross Chrome’s process trust boundary. According to the available vendor description, a remote attacker can trigger the issue with a crafted HTML page, but exploitation requires that the attacker has already compromised the renderer process through a separate vulnerability. The flaw was fixed in Chrome 147.0.7727.101/102 for Windows and macOS and 147.0.7727.101 for Linux and Android.
