CVE-2025-22403: 
NixOS vulnerability analysis and mitigation

CVE-2025-22403 is a critical vulnerability discovered in Android's Bluetooth implementation, specifically in the sdpsndservicesearchreq function of sdp_discovery.cc. The vulnerability was disclosed on August 26, 2025, and affects Android 15.0 operating system. This use-after-free vulnerability allows for arbitrary code execution without requiring additional execution privileges or user interaction (NVD, Android Bulletin).

The vulnerability exists in the sdp_discovery.cc component where log statements use structures that may have been freed by preceding calls, leading to a use-after-free condition. The vulnerability has received a CVSS v3.1 base score of 9.8 (CRITICAL) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating network accessibility, low attack complexity, and no required privileges or user interaction (NVD, Google Source).

The vulnerability can lead to remote code execution with no additional execution privileges needed. Due to its critical nature, successful exploitation could allow attackers to execute arbitrary code, potentially gaining complete control over the affected device. The vulnerability affects Android's Bluetooth stack, making it particularly concerning for all Android 15.0 devices (NVD, ASEC).

Google has released a security patch as part of the March 2025 security update. The fix involves using local variables instead of accessing potentially freed structures in the sdp_discovery.cc component. Users are strongly advised to update their Android devices to the latest security patch level dated 2025-03-05 (Android Bulletin, ASEC).
