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...

RustCrypto: Signatures has timing side-channel in ML-DSA decomposition

Summary A timing side-channel was discovered in the Decompose algorithm which is used during ML-DSA signing to generate hints for the signature. Details The analysis was performed using a constant-time analyzer that examines compiled assembly code for instructions with data-dependent timing...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: SCTP: The comparison of MACs has been fixed to require constant-time operations. To prevent timing attacks, MACs need to be compared in constant-time. Use the appropriate helper function for this purpose...

Memory Re-orderings as a Timerless Side-channel

Summary Researchers have provided AMD with a paper titled “MEMORY DISORDER: Memory Re-orderings as a Timerless Side-channel” In this work, the authors introduced MEMORY DISORDER, a timerless side-channel attack that exploits memory re-orderings to infer activity on other processes. They showed th...
