Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to convince the victim to install a malicious/crafted Chrome extension - that is the exact, concrete precondition stated in the CVE, and it is the primary factor limiting real-world exploitation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals point to a serious-but-not-urgent priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker publishes or distributes a malicious Chrome extension (e.g., disguised as a useful tool) and social-engineers a victim into installing it. Once loaded, the extension issues a crafted sequence that triggers the use-after-free in the Extensions component, reallocates the freed memory with controlled data, and gains arbitrary code execution in the browser context. … |
| Remediation | Vendor-released patch: Chrome 150.0.7871.47 - upgrade all desktop Chrome installations to 150.0.7871.47 or later, which for most users occurs automatically; force the update via chrome://settings/help and restart the browser, then confirm the version. … Detailed patch versions, workarounds, and compensating controls in full report. |
