libcrux-secrets is vulnerable to Incorrect Comparison
82
High Risk
This Affects:
libcrux-secretsTL;DR
A flaw in the constant-time swap and select implementations on AArch64 platforms could cause incorrect results due to an improper comparison in inline assembly. The comparison instruction evaluated unintended high-order bits of an 8-bit selector, potentially causing the operation to produce incorrect output under certain execution environments. Applications relying on these primitives for cryptographic operations could be affected by incorrect behavior.
