Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read via the GOOSE payload parser. An attacker can cause the subscriber process to terminate by sending a specially crafted unauthenticated Layer 2 multicast frame with an attacker-controlled inner element length that...

EUVD-2026-51359

The GOOSE subscriber component improperly validates the UTC timestamp field in unauthenticated IEC 61850 GOOSE EtherType 0x88B8 Layer-2 multicast messages. A specially crafted GOOSE frame containing an undersized timestamp field can trigger a heap out-of-bounds read during message processing,...

EUVD-2026-51341

The GOOSE payload parser contains a boundary handling flaw that can be triggered by a single unauthenticated Layer 2 multicast frame on the process bus. When processing specific payload fields, an attacker controlled inner element length may exceed its enclosing length, causing the parser to over...

CVE-2026-66720

The GOOSE subscriber component improperly validates the UTC timestamp field in unauthenticated IEC 61850 GOOSE EtherType 0x88B8 Layer-2 multicast messages. A specially crafted GOOSE frame containing an undersized timestamp field can trigger a heap out-of-bounds read during message processing,...

CVE-2026-66364
