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-2026-51358

The GOOSE parser contains an off-by-one boundary-handling flaw that can be triggered by a single unauthenticated Layer-2 multicast frame on the process bus. When specific GOOSE message fields are processed, the parser advances its internal buffer position incorrectly, resulting in a heap...

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-2026-52134

CVE-2026-52134 affects libiec61850 v1.6, in the parseGoosePayload() function (/goose/goose_receiver.c). The issue allows bypassing authentication via captured GOOSE frames due to inadequate handling of replayed/stale frames in the GOOSE subscriber path, potentially delivering older state data to ...
