Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The victim must actively visit a crafted HTML page in Google Chrome on Android (UI:R), meaning the attacker cannot exploit this without some form of social engineering - such as a phishing link, malicious ad, or compromised website. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 6.5 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) is driven by the High confidentiality impact, but multiple converging signals indicate this is a routine-priority patch rather than an emergency. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious webpage containing specially crafted HTML or WebGPU shader content designed to trigger the out-of-bounds read in Tint. When an Android Chrome user visits this page via a phishing link, malvertising redirect, or compromised site, the browser processes the content and Tint reads beyond a buffer boundary, potentially returning sandbox memory contents to the attacker. … |
| Remediation | Update Google Chrome for Android to version 152.0.7977.65 or later, which contains the vendor-released patch per the stable channel advisory at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
