CVE-2026-42285
HIGH7.5EPSS 0.18%GoBGP has a panic in AdjRib.Update via malformed BGP Update message (Nil Pointer Dereference)
發布日:2026/5/5修改日:2026/5/19
描述
GoBGP is an open source Border Gateway Protocol (BGP) implementation in the Go Programming Language. In version 4.4.0, an unauthenticated remote BGP peer can trigger a fatal panic in GoBGP by sending a specially crafted BGP UPDATE message. When the server receives a message with inconsistent attribute lengths, it improperly handles the internal state transition to a "withdraw" action, leading to a nil pointer dereference in the AdjRib.Update function. This causes the entire GoBGP process to crash, resulting in a complete loss of service availability. This issue has been patched in version 4.5.0.
