Analysis

Impact

The vulnerability involves an out‑of‑bounds read (CWE‑125) and is also classified under CWE‑787 (out‑of‑bounds write) in the Chromium Chromecast component of Google Chrome. A local attacker can send crafted network traffic that triggers a read of memory beyond the intended bounds, exposing sensitive data from the browser’s process memory. Additionally, the CWE‑787 classification indicates a potential for a buffer overflow that an attacker might exploit to affect adjacent memory regions.

Affected Systems

Users of Google Chrome older than version 150.0.7871.47 are affected. The issue was fixed in release 150.0.7871.47.

Risk and Exploitability

The CVSS score of 5.7 indicates low to moderate severity, and the EPSS score of less than 1% shows a low probability of exploitation. The flaw is local; it requires the attacker to influence traffic to the affected machine. Given that it is not listed in the CISA KEV catalog, no widespread exploitation is reported.

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