DescriptionCVE.org

Buffer overflow in WebGL in Google Chrome on on Android prior to 153.0.8010.52 allowed a remote attacker to execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: Critical)

AnalysisAI

Remote code execution outside the browser sandbox in Google Chrome on Android prior to 153.0.8010.52 is possible when a victim opens a crafted HTML page containing malicious WebGL content that triggers a stack-based buffer overflow. Unauthenticated remote attackers can achieve code execution in the context of the GPU/renderer process with high impact to confidentiality, integrity, and availability, though exploitation requires user interaction (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H, 9.6, Chromium security severity Critical). …

Vulnerability AssessmentAI

Exploitation Requires the victim to open a crafted HTML page in Google Chrome on Android prior to 153.0.8010.52 (UI:R); the page must contain malicious WebGL content that triggers the stack buffer overflow. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuine high-priority vulnerability. … 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 on Android to version 153.0.8010.52 or later; the vendor-released patch is documented in the stable channel update at https://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0194356994.html, and updates typically propagate through Google Play, so administrators should verify the installed build number in Chrome's Settings > About Chrome rather than assume automatic delivery. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, identify all Android devices running Google Chrome versions earlier than 153.0.8010.52 and immediately update them to the vendor-released patch: 153.0.8010.52 via Google Play or managed enterprise deployment; communicate to users that opening untrusted links in Chrome on unpatched Android devices carries critical risk. …
