CVE-2026-102824

Russh is a Rust SSH client and server library. Prior to 0.63.0, the hybrid ML-KEM 768 and X25519 implementation in russh/src/kex/hybridmlkem.rs accepts an all-zero 32-byte peer X25519 public key in both serverdh and computesharedsecret, forcing the X25519 contribution to the combined shared secre...

CVE-2026-102822

Russh is a Rust SSH client and server library. Prior to 0.63.1, a connection configured to permit mac=none can negotiate it with a MAC-requiring CTR or CBC block cipher because the selection logic validates needsmac only when MAC selection fails. A remote peer can then send a packet with a...
