Analysis

Impact

An integer overflow in the Chromecast component of Google Chrome, present in all versions prior to 150.0.7871.47, can be triggered by malicious network traffic. The flaw causes a bounds‑checking failure that corrupts memory and allows a local attacker to execute arbitrary code in the context of the user running Chrome. The flaw is classified as a CWE-122 Buffer Overflow, and the CVE data does not describe any escalation beyond the user’s existing privileges, so the impact is confined to the Chrome process and the user’s account.

Affected Systems

Google Chrome on Windows, macOS, Linux, and other supported platforms installed before version 150.0.7871.47 are affected. The issue is resolved in the June 2026 stable channel update and subsequent releases.

Risk and Exploitability

The base CVSS score is 8.8, indicating high impact. The EPSS score is below 1 %, and the CVE is not listed in CISA KEV, implying that active exploitation is currently unlikely. The attack vector is local; an attacker must send crafted Chromecast packets to a running Chrome process on the target machine to trigger the overflow. Successful exploitation results in arbitrary code execution in the context of the Chrome user.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
