AI Analysis

Impact

A use‑after‑free flaw in Chrome’s Canvas implementation lets an attacker craft a malicious HTML page that can trigger the dereferencing of freed memory. This can lead to arbitrary code execution inside Chrome’s sandboxed rendering process. The vulnerability is identified as CWE‑416, indicating that a program attempts to access memory that has already been freed.

Affected Systems

All desktop versions of Google Chrome released before 155.0.8059.79, regardless of platform, are affected.

Risk and Exploitability

The CVSS score of 8.8 indicates high severity. The EPSS score of less than 1 % points to a low probability of widespread exploitation at the time of analysis. The vulnerability is not listed in CISA’s KEV catalog. The attack vector is inferred to be a web‑based exploitation scenario, where an attacker would need to drive the user to a specially crafted web page. If triggered, the code runs with sandbox privileges, but the CVE description does not claim a sandbox escape to system-level privileges.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Update Google Chrome to version 155.0.8059.79 or newer; this version removes the Canvas use‑after‑free flaw.
  • If Site Isolation is not enabled, enable Chrome’s Site Isolation policy to isolate rendering processes, reducing potential impact.
  • Apply a strict Content Security Policy that blocks inline script execution on canvas elements to diminish the chance of exploitation.
