CVE-2021-45687: 
Rust vulnerability analysis and mitigation

An issue was discovered in the raw-cpuid crate before 9.1.1 for Rust. If the serialize feature is used (which is not the default), a Deserialize operation may lack sufficient validation, leading to memory corruption or a panic (NVD, RustSec).

When the non-default serialize feature is activated, most structs implement serde::Deserialize without proper validation. This implementation flaw can break invariants in safe code, specifically causing undefined behavior in asstring() methods which use std::str::fromutf8_unchecked() internally, and can trigger panics due to failed assertions (RustSec Advisory).

The vulnerability can lead to two main impacts: memory corruption through undefined behavior in as_string() methods, and denial of service through panics caused by failed assertions (RustSec Advisory).

The issue has been patched in version 9.1.1 and later of the raw-cpuid crate. Users should upgrade to the patched version. Versions 3.1.0 and earlier are unaffected by this vulnerability (RustSec Advisory).
