Out of bounds write in ANGLE in Google Chrome prior to 152.0.7977.65 allowed a remote attacker to execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Out-of-bounds write in ANGLE (Chrome's graphics abstraction layer) prior to version 152.0.7977.65 enables remote attackers to execute arbitrary code outside the browser sandbox by serving a crafted HTML page. The vulnerability carries a CVSS score of 8.8 and targets Chrome's Almost Native Graphics Layer Engine, a critical rendering subsystem, making exploitation viable against any unpatched Chrome user who visits a malicious page. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must induce the victim to visit a crafted HTML page (UI:R per CVSS); no authentication or prior account access is required on the target system. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 (High) vector - AV:N/AC:L/PR:N/UI:R/S:U - indicates network-reachable, low-complexity, unauthenticated exploitation requiring only user interaction (visiting a page). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker serves a crafted HTML page containing malicious WebGL or canvas operations designed to trigger the out-of-bounds write in ANGLE during graphics processing. When a Chrome user visits the page, the corrupted memory state is leveraged to achieve code execution within the renderer process and subsequently escape the Chrome sandbox, resulting in arbitrary code execution at the operating system level. … |
| Remediation | Upgrade Google Chrome to version 152.0.7977.65 or later immediately; this version is confirmed by the vendor's stable channel release blog at chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html and NVD advisory at nvd.nist.gov/vuln/detail/CVE-2026-79127. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, communicate the immediate availability of Chrome version 152.0.7977.65 or later to all users and ensure automatic updates are enabled. …
