Impact

Use of an uninitialized variable in Chrome's audio element before build 156.0.8078.47 allows a remote attacker to read memory inside the sandbox via a crafted media file. This memory disclosure (CWE‑457) exposes potentially confidential data within the browser's sandbox. The vulnerability does not currently claim arbitrary code execution beyond the sandbox, but the leakage could assist a subsequent attack within the browser session.

Affected Systems

All versions of Google Chrome older than 156.0.8078.47 are affected. This includes desktop deployments on all operating systems and potentially mobile variants released before the listed build. Any user running those versions is vulnerable.

Risk and Exploitability

The CVSS score of 8.8 classifies the vulnerability as high severity. The EPSS score is < 1 %, and the flaw is not listed in the CISA KEV catalog, indicating no confirmed exploitation yet; however, the likely attack vector is remote, requiring only that a victim visit a crafted HTML page. This makes the flaw attractive to attackers and emphasizes the need for prompt remediation.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade Google Chrome to release 156.0.8078.47 or later to receive the security fix
  • If an immediate upgrade is not feasible, block or disable Chrome's audio feature using appropriate flags to reduce the attack surface
  • For organizations, enforce HTTPS‑only browsing and network filtering to prevent delivery of malicious HTML content to unwary users
