Integer overflow in Compositing in Google Chrome prior to 153.0.8010.47 allowed a remote attacker to obtain cross-origin data via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
An integer overflow in Google Chrome's Compositing component (fixed in 153.0.8010.47) lets a remote attacker leak cross-origin data by getting a victim to open a crafted HTML page. Exploitation requires user interaction (the victim must load the page) but no authentication or elevated privileges, and the impact is limited to confidentiality - integrity and availability are unaffected per the CVSS vector. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a victim to render an attacker-controlled HTML page in a Google Chrome build older than 153.0.8010.47 (CVSS UI:R) - the crafted page must exercise Chrome's Compositing code path with values that overflow the relevant integer arithmetic, and the victim must not be running a patched build. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals here are consistent but point to a moderate-to-low real-world risk: CVSS 3.1 scores 4.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N), meaning the attacker needs a victim to visit a crafted page (UI:R) and gains only low-confidentiality cross-origin data, not code execution. … 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 | Upgrade Google Chrome to version 153.0.8010.47 or later - this is the fixed build identified by the vendor advisory (https://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0541751186.html); Chrome's automatic updater should deliver it, but verify via chrome://version and force a restart of all browser processes because a running instance continues to use the vulnerable compositor binary. … Detailed patch versions, workarounds, and compensating controls in full report. |
