rust-smallbitvec: smallbitvec is a growable bit-vector for Rust, optimized for size
CVE-2026-44983 is fixed in rust-smallbitvec on 1 platform by DEBIAN-CVE-2026-44983 (version 2.6.1-1), released June 24, 2026. It is not reported as exploited. Patch Radar priority: High.
smallbitvec is a growable bit-vector for Rust, optimized for size. From 1.0.1 to 2.6.0, an integer overflow in the internal capacity calculation of smallbitvec can lead to an undersized heap allocation, resulting in a heap buffer overflow through safe APIs only. This allows memory corruption without requiring unsafe code from the caller. This vulnerability is fixed in 2.6.1.
