Impact

Use after free in a Chrome SVG renderer can be triggered by a crafted HTML page, allowing a remote attacker to execute arbitrary code inside the browser sandbox. This critical flaw exposes users to code execution within the sandbox; the assigned CVSS score of 8.8 reflects the high severity of this vulnerability.

Affected Systems

Google Chrome on all platforms, versions earlier than 155.0.8059.79, are vulnerable. The issue affects every user running a pre‑155.0.8059.79 release on Windows, macOS, Linux, and Android.

Risk and Exploitability

The flaw was rated with a CVSS score of 8.8 and an EPSS probability of less than 1 %. It is not currently listed in CISA’s KEV catalog. Based on the description it is inferred that an attacker only needs to host or send a malicious SVG‑inspired HTML page to a victim, and no privileged access is required. The available control surface is within the browser sandbox, so the risk is limited to code execution inside that boundary. Given the low EPSS but high impact, the vulnerability poses a significant risk in environments where users routinely visit untrusted sites or open unknown files.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade Google Chrome to version 155.0.8059.79 or later, which contains the fixed SVG renderer.
  • If an immediate update is not feasible, disable or limit SVG rendering by using Chrome policy settings or flags that block untrusted SVG content.
  • Continuously monitor Google Chrome release notes and security advisories for follow‑up fixes or further mitigations.
