GHSA-PWHF-7427-9VV2

Vulnerability from github – Published: 2021-08-25 20:56 – Updated: 2023-06-13 16:46

Summary

Non-atomic writes in cgc

Details

Multiple soundness issues in `Ptr` in cgc

Affected versions of this crate have the following issues:

Ptr implements Send and Sync for all types, this can lead to data races by sending non-thread safe types across threads.
Ptr::get violates mutable alias rules by returning multiple mutable references to the same object.
Ptr::write uses non-atomic writes to the underlying pointer. This means that when used across threads it can lead to data races.

Severity

5.9 (Medium)
