Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Cryptographic Issues: Improper initialization of the receiver point in MultiScalarMult allows the generation of invalid points that falsely compare Equal to all other points, resulting in severe logic flaws during cryptographic verification. This is tracked under CVE-2026-26958.
Memory Corruption: Argument and receiver aliasing in field arithmetic functions like SqrtRatio can cause memory corruption and incorrect computational outputs unless intermediate elements are explicitly allocated on the heap rather than reused in-place.
