CVE-2026-9120 is a high-severity use-after-free vulnerability in the WebRTC component of Google Chrome. It affects Chrome versions prior to 148.0.7778.179, with Linux specifically noted as fixed in 148.0.7778.178. The flaw can be triggered when a victim visits a crafted HTML page, causing Chrome to access a WebRTC object after it has been freed. This stale-pointer dereference can allow attacker-controlled data to occupy the reclaimed memory region and be processed as a valid object, leading to memory corruption and arbitrary code execution within the browser process context. Chromium rated the issue High severity and assigned CVSS v3.1 vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H.
