CVE-2026-50185: Reliance on Undefined, Unspecified, or Implementation-Defined Behavior

RustCrypto CMOV provides conditional move CPU intrinsics which are guaranteed on major platforms to execute in constant-time and not be rewritten as branches by the compiler. From 0.1.1 until 0.5.4, the aarch64 implementations of Cmov and CmovEq in cmov/src/backends/aarch64.rs assume high bits ar...

Cmov/CmovEq on aarch64 can produce wrong results if high-bits of registers are set

Summary The aarch64 implementations of Cmov and CmovEq seem to assume that the high bits when loading a value of size smaller than a register into a register are zero-extended. However, this is not the case and these bits are unspecified. This can result in a left.cmovz&right, condition not movin...
