      "scenario": "AV:N - RDS over TCP exposes a kernel listener on TCP port 16385, and unauthenticated remote peers can drive the connection state changes that lead through rds_tcp_state_change(), rds_conn_path_drop(), and rds_conn_shutdown().\nAC:L - The attacker can repeatedly create/drop TCP connections or induce reconnect races; the stale pending-bit condition is reachable through normal connection-management timing and does not depend on an uncontrollable environment condition.\nPR:N - The network path accepts TCP peers before any RDS-level authentication or credential check, so a remote attacker needs no local account or privileges.\nUI:N - No victim user action is required once RDS TCP is enabled and reachable; the attacker only needs to interact with the exposed RDS TCP service.\nS:U - The impact remains within the kernel/RDS networking service security authority and does not cross a VM, sandbox, IOMMU, or similar boundary.\nC:N - The bug is a stale connection-management flag that suppresses reconnect scheduling; it does not expose memory contents or provide an information disclosure primitive.\nI:N - The issue does not corrupt memory or allow attacker-controlled modification of kernel or application data; it only affects reconnection behavior.\nA:H - Leaving RDS_RECONNECT_PENDING set can prevent future reconnect scheduling indefinitely, making the affected RDS path or peer connection unavailable until administrative recovery or another reset. In a critical RDS deployment this can fully deny communication to that peer, so high availability impact is appropriate."
