CVE-2023-2723Network attack vector

Renderer-to-browser heap corruption via DevTools use-after-free

Published May 16, 2023 · Updated May 5, 2025

Use-after-free in Google Chrome DevTools before 113.0.5672.126 allows remote attackers to corrupt browser-process heap memory via crafted HTML. The public record identifies DevTools as the lifetime-management locus but does not disclose the freed object, stale reference, or triggering code path. Exploitation requires a compromised renderer process and user interaction with crafted HTML; impact beyond heap corruption is not publicly established.
