CVE-2026-44983 not yet assigned priority: Debian including 1 source packages (rust-smallbitvec), 4 status rows across 4 suites (bookworm, forky, sid, trixie): open 2, resolved 2.
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.
