CVE-2026-9982: Insufficient validation of untrusted input in Google Chrome
CVE-2026-9982 is a high-severity vulnerability in Google Chrome prior to version 148.0.7778.216. It involves insufficient validation of untrusted input in the ANGLE component, which could allow a remote attacker who has compromised the renderer process to potentially escape the sandbox via a crafted HTML page. This vulnerability has a CVSS score of 8.3, indicating a significant risk. There are no known exploits in the wild at this time. The vendor advisory indicates the issue is addressed in Chrome version 148.0.
AI Analysis
Technical Summary
This vulnerability arises from insufficient validation of untrusted input within the ANGLE component of Google Chrome before version 148.0.7778.216. An attacker who has already compromised the renderer process could leverage this flaw to perform a sandbox escape by delivering a specially crafted HTML page. The sandbox escape could lead to elevated privileges and broader system compromise. The CVSS score of 8.3 reflects high impact on confidentiality, integrity, and availability, with network attack vector and user interaction required.
Potential Impact
Successful exploitation allows a remote attacker with control over the renderer process to escape the Chrome sandbox, potentially leading to full system compromise. This elevates the risk from a renderer compromise to a more severe security breach affecting the host system's security boundaries.
Mitigation Recommendations
Google has released an update in Chrome version 148.0.7778.216 that addresses this vulnerability. Users and administrators should update to this version or later to remediate the issue. There is no indication that additional mitigation steps are required beyond applying the official update.
