russh: negotiating a MAC-requiring block cipher (CTR/CBC) with mac=none causes a slice-index-out-of-range panic

Summary SshBlockCipher implementations AES-CBC, AES-CTR, 3DES-CBC, etc. report needsmac == true, meaning they are documented/intended to always be paired with a separate integrity MAC. However, key-exchange negotiation only checks needsmac inside the fallback branch of MAC algorithm selection use...

CVE-2026-102822

The russh Rust SSH client and server library is vulnerable to a slice-index-out-of-range panic in versions prior to 0.63.1 . The root cause is a flaw in the selection logic where a connection configured to permit mac=none can incorrectly negotiate a MAC-requiring CTR or CBC block cipher. An attac...

CVE-2026-102822 russh: negotiating a MAC-requiring block cipher (CTR/CBC) with mac=none causes a slice-index-out-of-range panic

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...

CVE-2026-102507

Sliver C2 framework version 1.7.7 and earlier contains an unhandled panic vulnerability in the operator gRPC handler that allows an attacker controlling a compromised implant to crash the entire teamserver by returning a malformed or empty Download response. Attackers can send zero-length or 1-3...
