Incorrect authorization in GPU in Google Chrome on on Mac prior to 153.0.8010.36 allowed a remote attacker who had compromised the renderer process to potentially obtain cross-origin data via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Incorrect GPU authorization in Google Chrome on macOS (prior to 153.0.8010.36) allows an attacker who has already compromised the renderer process to read cross-origin data by directing the victim to a crafted HTML page. This is a second-stage, chained vulnerability - not an initial access primitive - requiring prior renderer compromise and user interaction, which constrains its practical exploitability. …

Vulnerability AssessmentAI
| Exploitation | Two chained prerequisites are required: (1) the attacker must have already achieved code execution in the Chrome renderer process through a separate vulnerability; (2) the victim must be directed to and render a crafted HTML page while using Chrome on macOS. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is low, consistent with the CVSS 3.1 score and Chromium's own Medium rating. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Update Google Chrome on macOS to version 153.0.8010.36 or later via the stable channel release documented at https://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0808145027.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
