CVE-2026-47249

CVE-2026-47249 affects Klever-Go KVM (Go implementation of Klever) prior to v1.7.18. The issue is in P2P resolver request handling where a compressed RequestDataType_HashArrayType direct request (wire size ~442 bytes) can expand into about 200,000 decoded hash entries inside the resolver path. Th...

GHSA-W342-MJ6G-V9C4 Klever-Go KVM: Hash-array amplification in P2P resolver request handling

Summary A connected peer can send a compressed RequestDataTypeHashArrayType direct request that is only 442 bytes on the wire but expands into 200000 decoded hash entries inside the resolver path. On klever-go v1.7.17, this allows remote memory and CPU amplification against nodes that accept P2P...
