No local access is needed.\nAC:L - The code path is reached by an ordinary named-pipe open that the attacker issues at will, and the allocation-failure condition is one a remote attacker can drive on the memory-constrained embedded NAS/router platforms where ksmbd is typically deployed, by flooding connections, sessions and large request buffers.\nPR:N - Opening srvsvc/wkssvc/lsarpc on IPC$ is the classic SMB null-session path, and ksmbd\u0027s commonly shipped `map to guest = bad user` configuration lets an unauthenticated client obtain a guest session, tree-connect IPC$ and reach `create_smb2_pipe()` without any valid credentials.\nUI:N - The entire sequence (negotiate, session setup, tree connect to IPC$, SMB2_CREATE on a pipe) is initiated by the attacker against a listening server; no action by any local user or administrator is required.\nS:U - The leaked kernel object, the leaked IPC ID and the orphaned RPC handle all remain within the ksmbd server\u0027s own security authority; no VM, IOMMU or sandbox boundary is crossed.\nC:N - Nothing is read out of bounds and no kernel data is returned to the client; the client only learns an IDA-allocated small integer handle, which discloses no kernel memory contents or addresses.\nI:N - No memory is corrupted and no file or session data is modified \u2014 the ID is simply absent from the XArray, causing subsequent RPC operations on that handle to fail cleanly rather than alter state.\nA:H - Each occurrence permanently leaks a kernel slab object and a global IPC ID, and leaves an RPC pipe open forever in ksmbd.mountd because `ksmbd_session_rpc_close()`/`__session_rpc_close()` can never find the entry, so a remote attacker can repeatedly compound the leak into unrecoverable memory and handle exhaustion that takes the SMB server (and, on small-memory appliances, the system) down."
