CVE-2026-15122: Insufficient validation of untrusted input in Google Chrome
CVE-2026-15122 is a high-severity vulnerability in Google Chrome on Windows involving insufficient validation of untrusted input in the Codecs component. This flaw allows a remote attacker who has already compromised the renderer process to potentially escape the sandbox by using a specially crafted HTML page. The vulnerability affects Chrome versions prior to 150.0.7871.115. No explicit patch status is confirmed from the provided data, but a vendor advisory URL is available for further details.
AI Analysis
Technical Summary
This vulnerability arises from insufficient validation of untrusted input within the Codecs component of Google Chrome on Windows platforms. An attacker with control over the renderer process could exploit this flaw to perform a sandbox escape, which would increase their privileges and potentially allow further system compromise. The issue affects Chrome versions before 150.0.7871.115. Although no CVSS score is provided, the Chromium security team rates this vulnerability as high severity. The vendor advisory linked may contain patch or mitigation details, but these are not explicitly stated in the input data.
Potential Impact
Successful exploitation enables a remote attacker who has compromised the renderer process to escape the sandbox environment. This escalation can lead to increased privileges beyond the renderer sandbox, potentially allowing broader system access or control. The impact is significant given the sandbox is a key security boundary in Chrome.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_01162222768.html for current remediation guidance. Until official fixes are confirmed and applied, users should exercise caution with untrusted content. No vendor advisory content explicitly states 'no action required' or 'already mitigated'.
