CVE-2025-48751: 
Rust vulnerability analysis and mitigation

CVE-2025-48751 is a vulnerability discovered in the processlock crate version 0.1.0 for Rust programming language. The vulnerability was disclosed on May 23, 2025, and involves data races in the unlock functionality. This security issue affects applications using the processlock crate for process synchronization (CVE Details, MITRE).

The vulnerability is classified as a Concurrent Execution using Shared Resource with Improper Synchronization (Race Condition) issue, identified as CWE-362. The CVSS v3.1 base score is 2.9 (LOW), with the vector string CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L. The issue stems from the unlock function not being properly marked as unsafe, which can lead to data races when users perform unlock operations unexpectedly (CVE Details).

The vulnerability can result in data races within applications using the process_lock crate, potentially leading to synchronization issues and application instability. While the CVSS score indicates a low severity, the impact is primarily focused on availability rather than confidentiality or integrity (CVE Details).

The issue can be addressed by marking the unlock function as unsafe explicitly, following the pattern established in the lock-api crate. Users are advised to update to newer versions of the process_lock crate once a fix is available (GitHub Issue).
