CVE-2024-27218 is an information disclosure vulnerability identified in Google Android version 13. The root cause is an out-of-bounds read in the update_freq_data function, which occurs because of a missing bounds check on input data. This flaw allows a local attacker to read memory beyond the intended buffer limits, potentially exposing sensitive information stored in adjacent memory regions. The vulnerability does not require any privileges or user interaction, making it easier to exploit by local adversaries who have access to the device. The CVSS v3.1 base score is 6.2, reflecting a medium severity level primarily due to the high confidentiality impact but no impact on integrity or availability. The vulnerability is categorized under CWE-125, which involves improper validation of array indices leading to out-of-bounds reads. While no public exploits have been reported, the flaw could be leveraged in targeted attacks to extract sensitive data from affected Android 13 devices. No official patches have been linked yet, so users and administrators should remain vigilant. This vulnerability highlights the importance of rigorous input validation and bounds checking in system components handling frequency data or similar inputs.

The primary impact of CVE-2024-27218 is the potential unauthorized disclosure of sensitive information from affected Android 13 devices. Since the vulnerability allows out-of-bounds reads without requiring privileges or user interaction, local attackers with access to the device could exploit it to leak confidential data. This could include cryptographic keys, personal user data, or other sensitive information residing in memory near the vulnerable buffer. Although the vulnerability does not affect system integrity or availability, the confidentiality breach could facilitate further attacks such as privilege escalation or identity theft. Organizations relying on Android 13 devices, especially those handling sensitive or regulated data, face increased risks of data leakage and privacy violations. The lack of known exploits in the wild currently limits immediate widespread impact, but the vulnerability remains a significant concern until patched.

1. Monitor official Google Android security bulletins and apply security patches promptly once available to address CVE-2024-27218. 2. Limit local access to Android 13 devices by enforcing strong physical security controls and restricting access to trusted users only. 3. Employ mobile device management (MDM) solutions to enforce security policies and monitor for suspicious local activity that could indicate exploitation attempts. 4. Encourage users to avoid installing untrusted applications or software that could leverage local access to exploit this vulnerability. 5. For organizations with high-security requirements, consider deploying additional endpoint protection tools capable of detecting anomalous memory access patterns. 6. Conduct regular security assessments and penetration tests on Android devices to identify potential exploitation vectors related to local vulnerabilities. 7. Educate users about the risks of local attacks and the importance of device security hygiene to reduce the attack surface.
