WS-2022-0129

Date: August 19, 2025

Channel creates zero value of any type. Affected versions of this crate called mem::zeroed() to create values of a user-supplied type T. This is unsound e.g. if T is a reference type (which must be non-null). The flaw was corrected by avoiding the use of mem::zeroed(), using MaybeUninit instead.

Language: RUST
