CVE-2026-49837

A flaw was found in GoBGP, an open-source Border Gateway Protocol BGP implementation. A remote attacker could send a specially crafted BGP OPEN message, causing the BGP OPEN capability parser to misinterpret data. This issue arises because the parser may read capability values beyond their declar...

CVE-2026-49837

GoBGP is an open source Border Gateway Protocol BGP implementation in the Go Programming Language. Versions prior to 4.6.0 contain a BGP OPEN capability parsing issue where several concrete capability decoders may parse data from the full remaining capability buffer instead of the slice bounded b...

CVE-2026-49837

GoBGP (open source BGP implementation in Go) versions prior to 4.6.0 contain a boundary validation flaw in the BGP OPEN capability parser. Several capability decoders read from the full remaining buffer instead of the slice bounded by the declared CapLen , allowing a malformed OPEN message to cau...

CVE-2026-49837 GoBGP: BGP OPEN capability parser may read capability values outside declared CapLen boundaries

GoBGP is an open source Border Gateway Protocol BGP implementation in the Go Programming Language. Versions prior to 4.6.0 contain a BGP OPEN capability parsing issue where several concrete capability decoders may parse data from the full remaining capability buffer instead of the slice bounded b...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read in the BGP OPEN capability parsing process. An attacker can influence peer AS validation and capability negotiation by sending a specially crafted BGP OPEN message with a malformed capability length, causing the parse...
