rust-russh: Russh is a Rust SSH client and server library
CVE-2026-102825 is fixed in rust-russh on 1 platform by DEBIAN-CVE-2026-102825 (version 0.64.1-1), released October 16, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Russh is a Rust SSH client and server library. Prior to 0.62.6, the USERAUTH_REQUEST path reached from server::run_stream in russh/src/server/encrypted.rs increments self.common.auth_attempts but never compares it with server::Config.max_auth_attempts. An unauthenticated remote client can continue submitting authentication requests on one connection beyond the configured cap, bypassing the deployment's attempt-limiting policy and increasing online guessing opportunity and backend authentication workload. This issue is fixed in version 0.62.6.
