- Summary
- Use of Uninitialized Resource in smallvec
- Details
-
Affected versions of this crate called mem::uninitialized() 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 and thus may not remain uninitialized). The flaw was corrected by avoiding the use of mem::uninitialized(), using MaybeUninit instead.
