Impact

This vulnerability is a use‑after‑free bug in the Cast component of Google Chrome that can be triggered by crafted network traffic. The flaw allows an adjacent attacker to potentially execute arbitrary code outside of the browser sandbox, giving them the ability to compromise confidentiality, integrity, and availability of the affected system.

Affected Systems

The bug affects all versions of Google Chrome prior to 153.0.8010.36. Users running older releases are at risk until they upgrade to the patched version.

Risk and Exploitability

Chromium labels the fix as critical, and the CVSS score is 8.3 with an EPSS score of < 1%. The vulnerability is not listed in the CISA KEV catalog. Exploitation requires an attacker to deliver crafted network traffic to the vulnerable Cast service. While the EPSS score indicates a low exploitation probability, the critical severity suggests that the bug is worth treating with high urgency for patching.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Update Chrome to version 153.0.8010.36 or later, where the use‑after‑free is fixed.
  • Restart Chrome to ensure the new code is loaded.
  • If a patch cannot be applied immediately, disable the Cast feature by launching Chrome with the --disable-cast-receiver flag or disabling the "Enable Cast Receiver" flag in chrome://flags, which reduces the attack surface until a fix is available.
