RUSTSEC-2026-0003 Non-constant-time code generation on ARM32 targets

Summary While the cmov crate has a special backend for aarch64 which uses special CSEL instructions, on 32-bit ARM it uses a portable pure Rust fallback implementation. This implementation uses a combination of bitwise arithmetic and core::hint::blackbox to attempt to coerce constant-time code...

CVE-2025-0647

In certain Arm CPUs, a CPP RCTX instruction executed on one Processing Element PE may inhibit TLB invalidation when a TLBI is issued to the PE, either by the same PE or another PE in the shareability domain. In this case, the PE may retain stale TLB entries which should have been invalidated by t...
