Vulnerability AssessmentAI

Exploitation	Exploitation requires the victim to load attacker-controlled content in a vulnerable Chrome build (prior to 151.0.7922.72) and requires the WebRTC code path to be reachable - WebRTC APIs are available to any page by default, so no special browser configuration is needed. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The signals partially conflict. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An attacker hosts a malicious web page (or injects a malicious ad/iframe into a legitimate site) containing crafted JavaScript that drives WebRTC into the vulnerable object-lifecycle path. When a victim running a pre-151.0.7922.72 Chrome visits, the use-after-free corrupts the heap and the attacker attempts to gain code execution or leak memory in the renderer. …
Remediation	Vendor-released patch: update Google Chrome to 151.0.7922.72 or later on the Stable desktop channel; the fix is delivered via Chrome's automatic updater, so verify at chrome://settings/help and relaunch to apply, since the update is inert until restart. … Detailed patch versions, workarounds, and compensating controls in full report.
