CVE-2026-15121: Use after free in Google Chrome
Use after free in WebRTC in Google Chrome prior to 150.0.7871.115 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)
AI Analysis
Technical Summary
This vulnerability is a use-after-free in the WebRTC implementation of Google Chrome versions before 150.0.7871.115. Exploitation requires user interaction (UI:R) and can be triggered remotely via a maliciously crafted HTML page. Successful exploitation could lead to arbitrary code execution within the sandboxed environment of the browser, impacting confidentiality, integrity, and availability. The CVSS vector indicates network attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, and high impact on confidentiality, integrity, and availability.
Potential Impact
An attacker who successfully exploits this vulnerability can execute arbitrary code inside the sandboxed environment of the affected Chrome browser. This could lead to unauthorized actions such as data theft, manipulation, or denial of service within the browser context. The impact is rated high due to the potential for full compromise of the browser process.
Mitigation Recommendations
Google has released a stable channel update that addresses this vulnerability. Users and administrators should update Google Chrome to version 150.0.7871.115 or later to remediate this issue. Patch status is not explicitly confirmed in the advisory content provided, but the linked vendor advisory corresponds to a stable update that includes this fix.
