CVE-2026-66369

The CVE-2026-66369 issue affects the GOOSE parser in the libiec61850 library used by MZ Automation. It is caused by an off-by-one boundary-handling flaw in the parser that can be triggered by a single unauthenticated Layer-2 multicast frame on the process bus, causing the parser to advance its in...

CVE-2026-66364 MZ Automation libiec61850 Out-of-bounds Read

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-2026-66364

CVE-2026-66364 affects the GOOSE payload parser (notably in the libiec61850/GOOSE implementation referenced by MZ Automation). The root cause is a boundary handling flaw: during processing of certain payload fields, an attacker-controlled inner element length may exceed its enclosing length, caus...

CVE-2026-66369: Out-of-bounds Read

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...

CVE-2026-66720: Out-of-bounds Read

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-2026-64423

A flaw was found in the Linux kernel's Internet Group Management Protocol IGMP multicast group handling. When a network device is destroyed, its associated multicast groups are not properly removed from the device's hash table before their memory is reclaimed. This creates a race condition where ...

CVE-2026-47180

A flaw was found in Zeroconf, a Python implementation of multicast DNS service discovery. An unauthenticated attacker on the local network can send a specially crafted multicast DNS mDNS packet with chained pointers. This can trigger a recursion error, leading to sustained CPU usage, excessive...

CVE-2026-48487

A flaw was found in Zeroconf, a Python library for multicast DNS service discovery. An unauthenticated attacker on the local network can exploit a vulnerability in how the system processes incoming DNS records. By sending a specially crafted record with an excessive length, the attacker can cause...
