AI Analysis

Impact

The flaw resides in the isValid function of ShimConverter.cpp where a missing bounds check allows an out‑of‑bounds memory read. An attacker with local device access can capture data beyond the intended buffer, revealing sensitive information without needing elevated privileges.

Affected Systems

Devices running Google Android are affected. The security bulletin does not list specific Android versions, so all releases prior to the patch issuance should be regarded as vulnerable until the update is applied.

Risk and Exploitability

The vulnerability requires local access and no special privileges, so remote exploitation is not possible. The EPSS score is not available, and the vulnerability is not listed in the CISA KEV catalog. Exploitation would involve triggering ShimConverter in a way that causes the buffer over‑read, leading to information disclosure.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the latest Android security patch that fixes the ShimConverter bounds check.
  • If a patch is not yet available, uninstall or disable any applications that invoke ShimConverter functionality until a fix is released.
  • Monitor device logs for abnormal memory access patterns and review Google’s security bulletins for additional mitigation guidance.
