Type confusion in ANGLE in Google Chrome prior to 152.0.7977.65 allowed a remote attacker to potentially execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Type confusion in Chrome's ANGLE graphics abstraction layer (all versions prior to 152.0.7977.65) enables remote attackers to potentially execute arbitrary code outside the browser sandbox by directing a user to a specially crafted HTML page. The CVSS 8.8 score reflects network-accessible delivery with no privilege requirements, full confidentiality, integrity, and availability impact, though user interaction is necessary. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Active user interaction is required: the victim must navigate to an attacker-controlled or attacker-influenced HTML page (UI:R per CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The official CVSS 8.8 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) captures network reachability and full CIA impact but appears inconsistent with the description: the S:U (scope unchanged) designation conflicts with 'code execution outside the sandbox,' which by CVSS 3.1 convention warrants S:C (Changed), elevating the theoretical score to approximately 9.6 Critical. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious HTML page containing crafted WebGL or canvas-rendering content engineered to trigger the type confusion condition in Chrome's ANGLE layer. A victim on an unpatched Chrome version visits the page through a phishing email link or a malicious advertisement on a legitimate site, causing the GPU process to misinterpret a graphics object's memory type, corrupting memory state and potentially executing attacker-controlled code outside Chrome's sandbox at the privilege level of the logged-in user. … |
| Remediation | Update Google Chrome to version 152.0.7977.65 or later immediately, as confirmed by the vendor 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. |
Recommended ActionAI
Within 24 hours, deploy Chrome 152.0.7977.65 or later across all endpoints through your browser update system and notify users of the mandatory security update. …
