Severity by source
AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
Network-reachable via crafted page (AV:N, UI:R, PR:N) with sandbox-crossing scope change; AC:H reflects that reliable truncation-based sandbox escape typically needs specific conditions/chaining, consistent with Chromium's Medium rating.
Primary rating from Vendor (Chrome).

Numeric truncation error in Media in Google Chrome prior to 153.0.8010.36 allowed a remote attacker to potentially execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Sandbox-escape remote code execution in Google Chrome before 153.0.8010.36 stems from a numeric truncation error in the Media component, letting a remote attacker who lures a victim to a crafted HTML page potentially run arbitrary code outside the renderer sandbox. The vendor patch is available via the September 2026 stable-channel update; no public exploit is identified at time of analysis. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires the victim to open attacker-controlled web content (UI:R) in a vulnerable Chrome build (before 153.0.8010.36) that processes the crafted media triggering the truncation in the Media component - no authentication or prior privileges needed (PR:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The supplied CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H, 9.6) describes a network-reachable, low-complexity, unauthenticated sandbox escape requiring only that the user open a page - a serious profile because scope changes (S:C) reflect crossing the sandbox boundary. … 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 | Vendor-released patch: Google Chrome 153.0.8010.36. … Detailed patch versions, workarounds, and compensating controls in full report. |
