Loading vulnerability…
CVE-2026-9126 is a use-after-free vulnerability in the DOM component of Google Chrome affecting versions prior to 148.0.7778.178 on Linux and prior to 148.0.7778.178/179 on Windows and macOS. The flaw arises from incorrect lifetime management of DOM objects, allowing a stale reference to persist after the underlying object has been freed. A remote attacker can trigger the condition by causing a victim to load a crafted HTML page that manipulates DOM state in a way that leads to dereferencing of freed memory. Reuse of the freed heap region with attacker-influenced data can corrupt execution flow and result in arbitrary code execution within Chrome's renderer process. Chromium rated the issue Medium severity because exploitation is confined to the sandboxed renderer.
