AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Cast traffic requires adjacent-network position (AV:A) with no auth or interaction; a heap overflow yielding code execution gives full C/I/A impact.

Integer overflow in Chromecast in Google Chrome prior to 150.0.7871.47 allowed a local attacker to execute arbitrary code via malicious network traffic. (Chromium security severity: Medium)
AnalysisAI
Heap-based integer overflow in Google Chrome's Chromecast component allows an adjacent-network attacker to achieve arbitrary code execution against browsers running versions prior to 150.0.7871.47. The flaw is reachable via crafted malicious network traffic and carries a high CVSS of 8.8; Google has shipped a stable-channel fix, and no public exploit has been identified at time of analysis. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to reach the victim over the local/adjacent network (CVSS AV:A) and to deliver malicious traffic to Chrome's Chromecast component - implying the browser is processing Cast discovery or streaming traffic. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are mixed. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker on the same local network (e.g., a shared corporate LAN, guest Wi-Fi, or a compromised IoT device) sends specially crafted Cast/streaming traffic to a victim's Chrome browser. The malformed length field triggers the integer overflow and heap overflow in the Chromecast parser, corrupting memory and executing attacker-controlled code in the browser process without any user click. … |
| Remediation | Vendor-released patch: update Google Chrome to 150.0.7871.47 or later via the Stable Channel Update; most installations receive this through Chrome's automatic updater, so ensure auto-update is enabled and restart the browser to apply it (verify via chrome://settings/help). … Detailed patch versions, workarounds, and compensating controls in full report. |
