CVE-2026-113032: Improper input validation in Omnibox

Q: Which devices and configurations are affected?

The issue affects Google Chrome on Android versions prior to 156.0.8078.47. The provided information does not identify any configuration prerequisite, so Android Chrome installations below that version should be treated as potentially affected.

Q: What does an attacker need to exploit this issue?

An attacker needs to cause a user to load a crafted HTML page remotely. Successful exploitation can execute arbitrary code inside Chrome's sandbox.

Q: How can I determine whether an installation is affected?

Check the installed Google Chrome version on the Android device. Versions earlier than 156.0.8078.47 are affected according to the available information.

Q: What should be done if an affected version is deployed?

Update Google Chrome on Android to version 156.0.8078.47 or later. If updating cannot happen immediately, reducing exposure to untrusted or attacker-controlled web pages can limit the stated attack vector.
