Sandbox escape via compositing out-of-bounds write
Published Apr 10, 2024 · Updated Mar 27, 2025
Out-of-bounds write in Google Chrome before 123.0.6312.122 allows remote attackers to escape the browser sandbox through UI gestures. The Compositing component writes beyond a memory boundary when the already-compromised GPU process handles specific UI gestures; Google has not disclosed the affected function or buffer operation. Exploitation requires prior control of the GPU process and user interaction, and successful use crosses the sandbox boundary with confidentiality and availability impact.
