Sandbox escape via out-of-bounds write in Google Chrome GPU
CVE-2026-6314 is a high-severity out-of-bounds write vulnerability in the GPU component/process of Google Chrome. It affects Chrome versions prior to 147.0.7727.101, with fixed releases identified as 147.0.7727.101 for Linux and 147.0.7727.101/.102 for Windows and macOS. According to the provided content, a remote attacker can trigger the issue using a crafted HTML page, but exploitation is not single-stage: the attacker must first achieve compromise of the GPU process through a separate vulnerability or technique, then leverage the out-of-bounds write to corrupt memory in the GPU process and escape the sandbox. Publicly available material does not disclose the exact vulnerable function, buffer, or bounds-check failure, and Chromium issue details were restricted at disclosure time.
