Analysis

Impact

A heap buffer overflow exists in the Chromecast component of Google Chrome versions earlier than 150.0.7871.47. The flaw allows a remote attacker who has already compromised the renderer process to load a specially crafted HTML page that may provoke a sandbox escape, giving the attacker higher privileges within the browser process. The vulnerability does not guarantee control of the underlying operating system and requires an initial renderer-level compromise.

Affected Systems

All installations of Google Chrome on the stable desktop channel running a version earlier than 150.0.7871.47 are susceptible. The issue targets the Chromecast functionality built into the browser, affecting any user who has the Cast feature enabled on those legacy builds.

Risk and Exploitability

The CVSS score of 9.6 marks this flaw as critical, yet its EPSS score is below 1%, indicating a low probability of widespread exploitation. It is not listed in the CISA KEV catalog. Exploitation requires an initial renderer compromise, followed by delivery of malicious HTML content. The overall risk depends on how exposed users are to renderer-level attacks and the use of the Cast feature.

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

OpenCVE Recommended Actions

Upgrade Google Chrome to version 150.0.7871.47 or later to receive the heap overflow patch.
In enterprise environments, disable the Chromecast functionality through group policy or local settings to reduce attack surface.
Enforce an update policy that automatically installs the latest Chrome releases and blocks older, vulnerable versions from running.
