DescriptionCVE.org

Out of bounds read in ANGLE in Google Chrome prior to 153.0.8010.36 allowed a remote attacker who had compromised the renderer process to potentially execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: High)

AnalysisAI

Out-of-bounds read in ANGLE, Chrome's cross-platform graphics abstraction layer, enables sandbox escape and potential remote code execution on the host system for Chrome versions prior to 153.0.8010.36. This is a staged, second-phase exploit: an attacker must first compromise the renderer process through a separate vulnerability before leveraging this ANGLE flaw to break out of Chrome's sandbox via a crafted HTML page. …

Vulnerability AssessmentAI

Exploitation Exploitation requires two sequential conditions: first, the attacker must already have compromised Chrome's renderer process - this implies chaining with a separate, unspecified renderer vulnerability (not provided by this CVE). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 8.3 score (AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H) accurately captures the severity ceiling but requires critical contextual interpretation: AC:H reflects the real-world requirement for a pre-compromised renderer process, making this a chained, multi-stage attack rather than a standalone exploit. … 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 Update Google Chrome to version 153.0.8010.36 or later, which contains the vendor-released patch per the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0808145027.html. … Detailed patch versions, workarounds, and compensating controls in full report.
