CVE-2026-44983 High · 7.3 CWE-122 May 26, 2026
smallbitvec: Safe API Triggered Heap Buffer Overflow via Integer Overflow
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.
