AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
Network-reachable via a crafted page needing a click (UI:R), but reliably exploiting a use-after-free race is high complexity (AC:H); sandbox escape justifies S:C and full C/I/A impact.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to load attacker-controlled HTML in a vulnerable Chrome build (before 153.0.8010.36) - user interaction (UI:R) in the form of visiting a crafted page is the primary limiting factor; no authentication is required (PR:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H = 9.6) reflects a network-reachable, low-complexity, unauthenticated bug that requires user interaction (visiting a page) and crosses a security boundary (S:C, escaping the sandbox), yielding full confidentiality/integrity/availability impact. … 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: update Google Chrome to 153.0.8010.36 or later on all desktop platforms (Windows, macOS, Linux); the fix is delivered through the stable channel per Google's advisory (https://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0808145027.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
