CVE-2025-48752: 
Rust vulnerability analysis and mitigation

CVE-2025-48752 affects the process-sync crate version 0.2.2 for Rust. The vulnerability was discovered and published to the CVE List on May 23, 2025. The issue involves a missing check in the drop function for whether the pthread_mutex is unlocked (NVD).

The vulnerability is classified as CWE-416 (Use After Free). 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 technical issue stems from the drop function in the SharedMutex implementation, which fails to verify the lock status of the pthread_mutex before destruction (NVD, GitHub Issue).

The vulnerability could lead to undefined behavior when destroying a locked pthread_mutex, potentially causing application instability or crashes. The impact is considered low severity due to the local access requirement and high attack complexity (NVD).

A proper mitigation approach has been suggested, referencing the Rust standard library's implementation which includes appropriate checks before destroying the mutex. The recommended fix involves implementing similar checks as found in the Rust standard library's pthread mutex implementation (GitHub Issue).
