AI Analysis

Impact

A use‑after‑free flaw in Blink allows an attacker to cause execution of arbitrary code while the browser is still under sandbox protection. The flaw is activated by a specially crafted HTML document delivered from a remote source. If exploit succeeds, the attacker can run code within the browser process with elevated privileges, potentially compromising the host system.

Affected Systems

Google Chrome versions earlier than 150.0.7871.186 are vulnerable. Any user running the affected build on a desktop platform may be impacted.

Risk and Exploitability

The issue carries a CVSS score of 8.8, indicating high severity. Its EPSS score is below 1%, suggesting a low probability of widespread exploitation at present, and it is not listed in CISA’s KEV catalog. The likely attack path involves a remote attacker hosting a malicious HTML page that a victim’s Chrome browser will load, hence baseline protection is user level or network filtering.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Install Chrome stable 150.0.7871.186 or later to remove the use‑after‑free vulnerability
  • If an update cannot be performed immediately, block or restrict loading of untrusted web content by using network filtering or by configuring the browser to block scripting on unknown pages
  • Apply a content‑security‑policy that disallows inline scripts to reduce the impact of any residual exploitation attempt
  • Regularly check the Chrome release notes or vendor website for updated security fixes
