CVE-2026-11098 is a medium severity vulnerability in Google Chrome's GPU component affecting versions before 149.0.7827.53. It arises from insufficient validation of untrusted input, enabling a remote attacker with renderer process compromise to leak cross-origin data through a crafted HTML page. The CVSS 3.1 vector indicates network attack vector, high attack complexity, no privileges required, user interaction required, unchanged scope, and high confidentiality impact with no integrity or availability impact. The vulnerability is tracked under CWE-20 (Improper Input Validation). The vendor advisory link is available but does not explicitly state patch or remediation details.

An attacker who has already compromised the renderer process can exploit this vulnerability to leak sensitive cross-origin data, potentially exposing confidential information. The confidentiality impact is high, but integrity and availability are not affected. There are no known exploits in the wild at this time.

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.
