CVSS v3.1

9.8

Critical

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions: internment crate versions prior to 0.4.2

Description: The issue is related to a data race that can cause memory corruption due to the unconditional implementation of Sync for Intern<T>. This allows users to create a data race on T: !Sync, which may lead to undefined behavior, such as memory corruption.

Recommendations: For versions prior to 0.4.2, update to version 0.4.2 or later, which includes the correction by adding the trait bound T: Sync in the Sync impl of Intern<T>. As a temporary workaround, consider avoiding the use of Intern<T> with types that do not implement Sync to minimize the risk of exploitation.
