AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N
Browser sandbox limits readable memory to the renderer process, warranting C:L over C:H; all other metrics align with network delivery via crafted page requiring user navigation.

Integer overflow in WebNN in Google Chrome prior to 150.0.7871.47 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Integer overflow in Chrome's WebNN (Web Neural Network API) component prior to version 150.0.7871.47 enables remote attackers to read potentially sensitive data from browser process memory by luring a user to a crafted HTML page. The attack requires no privileges and no special configuration, but mandates user interaction - the victim must navigate to a malicious page. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target to be running Google Chrome prior to version 150.0.7871.47 on a desktop platform. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N yields a 6.5 Medium, with C:H implying significant confidentiality loss. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious HTML page that constructs WebNN tensor operations with input dimensions carefully sized to trigger an integer overflow in Chrome's WebNN implementation. When a target user visits the page with a vulnerable Chrome version, the overflow causes the WebNN subsystem to read from uninitialized or adjacent renderer-process memory, and the page's JavaScript receives and exfiltrates that memory content back to the attacker's server. … |
| Remediation | Upgrade Google Chrome to version 150.0.7871.47 or later - this is the vendor-released patch per the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
