Data races in rulinalg

Critical severity GitHub Reviewed Published Aug 25, 2021 to the GitHub Advisory Database • Updated Jun 13, 2023

Package

cargo rulinalg (Rust)

Affected versions

>= 0.4.0, <= 0.4.2

Patched versions

None

Description

The affected version of rulinalg has incorrect lifetime boundary definitions for RowMut::raw_slice and RowMut::raw_slice_mut. They do not conform with Rust's borrowing rule and allows the user to create multiple mutable references to the same location. This may result in unexpected calculation result and data race if both references are used at the same time.
