AI Analysis
Technical Summary
This vulnerability arises from improper validation of untrusted input in the Custom Tabs implementation of Google Chrome on Android versions before 149.0.7827.53. A local attacker can exploit this by crafting a malicious XML file to escalate privileges within the affected environment. The CVSS vector indicates the attack requires local access with low complexity, privileges, and user interaction, but results in high confidentiality, integrity, and availability impacts. The vendor advisory linked corresponds to a Chrome stable channel update, suggesting a fix may be included in or after version 149.0.7827.53, but explicit patch confirmation is not provided in the input.
Potential Impact
Successful exploitation allows a local attacker to escalate privileges on the affected Android device running Google Chrome, potentially leading to full compromise of confidentiality, integrity, and availability of the system or user data. The high CVSS score reflects significant impact if exploited.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html for current remediation guidance. Users should update Google Chrome on Android to version 149.0.7827.53 or later once available. Until then, limiting local access and avoiding opening untrusted XML files in Custom Tabs may reduce risk.
