CVE-2026-8001Network attack vector

Sandbox escape via Printing use-after-free

Published May 6, 2026 · Updated May 6, 2026

Use-after-free in Google Chrome Printing before 148.0.7778.96 on Linux, macOS, and ChromeOS allows remote attackers to escape the sandbox. Google identifies the fault only as a Printing use-after-free; the restricted Chromium issue does not publicly identify the freed object or stale access. Exploitation requires a crafted HTML page, user interaction, and prior compromise of the renderer process; success breaks the renderer sandbox boundary.
