Use-After-Free Vulnerability in Linux Kernel Affecting Binder Devices

CVE-2025-38175

What is CVE-2025-38175?

CVE-2025-38175 is a use-after-free vulnerability found in the Linux kernel related to Binder devices. The Linux kernel serves as the core component of Linux operating systems, facilitating interactions between hardware and software. This particular vulnerability arises when Binder devices are improperly managed, allowing for objects to be freed (deallocated) without being correctly removed from the device list. This oversight can lead to severe consequences, including the potential execution of malicious code due to memory corruption. The nature of such a vulnerability means that applications leveraging Binder services could be exposed to unexpected behavior, leading to crashes, data leakage, or unauthorized access to memory regions.

Potential Impact of CVE-2025-38175

1. Remote Code Execution: Attackers could exploit the use-after-free condition to manipulate memory, allowing them to execute arbitrary code on affected systems, potentially leading to full system compromise.

2. System Instability: The vulnerability could cause applications relying on Binder to behave unpredictably or crash completely, resulting in system outages that can impact business operations and service availability.

3. Data Integrity Risks: The mishandling of memory management could expose sensitive data to unauthorized access or corruption, jeopardizing data confidentiality and integrity for users and systems relying on the affected Linux kernel.
