AI Analysis

Impact

The vulnerability lies in the get_global_config_item_addr function of Android's gc.c module, where a missing bounds check allows an out‑of‑bounds read. Exploitation of this flaw can be performed by a local user without prior elevated rights, enabling access to privileged data and subsequent elevation of privileges. Because no additional execution privileges are required, the attack does not need arbitrary code execution, yet it compromises system integrity and confidentiality for the affected device.

Affected Systems

Android operating systems supplied by Google are impacted. No specific version numbers are listed in the advisory, so any device running a build that contains the unpatched gc.c code may be vulnerable.

Risk and Exploitability

Exploitation is local and does not require user interaction, making the attack vector straightforward. EPSS data is not available and the issue is not listed in CISA KEV, indicating that no public exploits have been documented at the time of this analysis. Nonetheless, the ability for a local user to gain elevation of privilege with minimal prerequisites places the risk in the high category for any affected device.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the latest Android security patch that contains the fix for the out‑of‑bounds read in gc.c
  • If a patch is not yet available, limit access to the affected component by running the device in a highly restricted mode that denies privileged operations
  • Keep the device subscribed to automatic security updates and monitor Android security bulletins for a future advisory that updates the fix
