AI Analysis

Impact

The vulnerability is a use‑after‑free flaw in Google Chrome’s Ozone windowing backend that exists in releases prior to version 150.0.7871.115. A maliciously crafted HTML page can trigger heap memory corruption, which may compromise data integrity or availability; the CVE description indicates that these conditions could lead to severe impact, although it does not guarantee arbitrary code execution.

Affected Systems

Google Chrome binaries released before 150.0.7871.115 on any operating system that uses the Ozone backend are affected. This includes all desktop deployments of Chrome and Chromium before that version across Windows, macOS, Linux, and other supported platforms.

Risk and Exploitability

The CVSS score of 8.8 marks this issue as high severity, while an EPSS score of <1% suggests that attacks are unlikely in the wild at this time. The vulnerability is not listed in CISA’s KEV catalog. The likely attack vector is a malicious website that a user visits and which serves a handcrafted HTML page to exploit the heap corruption. Applying the vendor’s patch removes the risk.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade Chrome to version 150.0.7871.115 or later; the update addresses the use‑after‑free in the Ozone backend.
  • Enable Chrome’s automatic updates so that future memory‑correction fixes are delivered without manual intervention.
  • If an immediate upgrade is impossible, isolate Chrome in a sandbox or enforce a restrictive browsing policy, and avoid opening unknown or suspicious HTML content to reduce exposure to the vulnerability.
