How to Fix CVE-2025-48752

To remediate this vulnerability, upgrade all affected Process sync dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

process-sync fixed: Latest secure release 
Upgrade process-sync to Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for process-sync

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-48752, inspect your project dependencies for Process sync:

inspect dependencies for process-sync

Analyze the terminal output to locate any version of Process sync in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-416: Use After Free, where the product reuses or references memory after it has been freed. at some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. In Process sync, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

In the process-sync crate 0.2.2 for Rust, the drop function lacks a check for whether the pthread_mutex is unlocked.
