CVE-2026-15904Network attack vector

Heap corruption via Ozone use-after-free

Published Jul 20, 2026 · Updated Jul 20, 2026

Use-after-free in Ozone in Google Chrome before 150.0.7871.128 on Linux allows remote attackers to corrupt heap memory through crafted HTML. Public records identify Ozone as the locus and access to freed memory as the faulty operation, but the restricted Chromium issue does not identify the affected object or code path. Exploitation requires a user to perform specific UI gestures on the crafted page and permits confidentiality, integrity, and availability impact within the browser context.
