Amazon Linux 2 : rust, --advisory ALAS2-2026-3296 (ALAS-2026-3296)

medium Nessus Plugin ID 314574

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of rust installed on the remote host is prior to 1.95.0-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3296 advisory.

Double-Free / Use-After-Free (UAF) in the `IntoIter::drop` and `ThinVec::clear` functions in the thin_vec crate. A panic in `ptr::drop_in_place` skips setting the length to zero. (CVE-2026-6654)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update rust' or or 'yum update --advisory ALAS2-2026-3296' to update your system.
