CVE-2019-16137: Spin-RS Project Spin-RS

High severity, CVSS 7.5. EPSS: 1.4% chance of exploitation in the next 30 days.

An issue was discovered in the spin crate before 0.5.2 for Rust, when RwLock is used. Because memory ordering is mishandled, two writers can acquire the lock at the same time, violating mutual exclusion.

Affected products

• Spin-RS Project Spin-RS: before 0.5.2 (fixed in 0.5.2)
