Sandboxed code execution via Media bounds error
Published Jun 8, 2026 · Updated Jun 8, 2026
Out-of-bounds read and write in Google Chrome Media before 149.0.7827.103 allows remote attackers to execute code inside the macOS sandbox. Google has not disclosed the affected Media code path or the operation that permits memory access beyond its buffer boundaries. Exploitation requires a crafted HTML page, user interaction, and prior compromise of the renderer process; the reported consequence remains confined to arbitrary code execution inside the browser sandbox.
