Uninitialized resource in Media in Google Chrome prior to 153.0.8010.36 allowed a remote attacker who had compromised the renderer process to read memory outside the sandbox via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Uninitialized resource use in Chrome's Media component (CVE-2026-87456) enables a renderer-compromised attacker to read memory outside the Chrome sandbox via a crafted HTML page, fixed in version 153.0.8010.36. This is a post-compromise, second-stage information disclosure capability rather than a standalone entry-point vulnerability - successful exploitation requires the attacker to have already achieved code execution within the renderer process through a separate exploit. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires two preconditions: (1) the victim must visit a crafted HTML page (UI:R), and (2) the attacker must have already compromised the Chrome renderer process through a separate, independent vulnerability - this is the primary limiting factor and what drives AC:H in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk for this CVE is low in isolation. … 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 via the browser's built-in update mechanism (Help > About Google Chrome) or managed enterprise deployment. … Detailed patch versions, workarounds, and compensating controls in full report. |
