Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N
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.
