rust-russh: Russh is a Rust SSH client & server library
CVE-2026-48107 is fixed in rust-russh on 1 platform by DEBIAN-CVE-2026-48107 (version 0.64.1-1), released June 10, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Russh is a Rust SSH client & server library. From version 0.37.0 to before version 0.61.0, in the russh client keyboard-interactive authentication path, a malicious SSH server could send a USERAUTH_INFO_REQUEST with an attacker-controlled prompt count, and the client would use that raw count directly in Vec::with_capacity(...) before validating that enough prompt data was actually present in the packet. This issue has been patched in version 0.61.0.
