The vendor advisory linked does not explicitly confirm patch availability or remediation status.
AI Analysis
Technical Summary
This vulnerability arises from insufficient validation of untrusted input within the WebAppInstalls feature of Google Chrome on Android versions before 148.0.7778.216. A local attacker could leverage this flaw by providing a malicious file to execute arbitrary code on the affected device. The CVSS vector indicates the attack requires local access with low complexity, no privileges, and user interaction, and it impacts confidentiality, integrity, and availability with high severity.
Potential Impact
Successful exploitation could lead to arbitrary code execution on the affected Android device, compromising confidentiality, integrity, and availability. This could allow an attacker to run malicious code with the privileges of the Chrome process, potentially leading to further system compromise.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory at https://chromereleases.googleblog.com/2026/05/stable-channel-update-for-desktop_0877304591.html for current remediation guidance. Until official confirmation of a fix, users should exercise caution with local file inputs and avoid untrusted files. Monitor for updates from Google and apply any released patches promptly.
