AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
Network-delivered but requires victim UI interaction (UI:R) and non-trivial UAF/sandbox-escape exploitation (AC:H); no auth (PR:N); sandbox escape gives scope change and full C/I/A impact.

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a remote attacker to deliver a malicious page to Google Chrome on Android (versions before 152.0.7977.65) AND to convince the victim, through social engineering, to perform a specific UI interaction that drives the vulnerable Sessions code path - the CVSS UI:R metric and the description's 'leveraging social engineering ... … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals here conflict and warrant scrutiny. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious web page and uses social engineering (e.g., a phishing message) to get an Android Chrome user to visit it and perform a specific UI action, such as interacting with a tab/session restore prompt. That interaction triggers the use-after-free in the Sessions component, letting the attacker's controlled data reclaim freed memory and execute code that escapes the sandbox. … |
| Remediation | Vendor-released patch: update Google Chrome on Android to 152.0.7977.65 or later via Google Play; this is the primary and complete fix. … Detailed patch versions, workarounds, and compensating controls in full report. |
