Summary

In the Linux kernel, the following vulnerability has been resolved: sunrpc: clear XPRT_SOCK_UPD_TIMEOUT when reset transport Since transport->sock has been set to NULL during reset transport, XPRT_SOCK_UPD_TIMEOUT also needs to be cleared. Otherwise, the xs_tcp_set_socket_timeouts() may be triggered in xs_tcp_send_request() to dereference the transport->sock that has been set to NULL.

An on-path attacker injecting RSTs into a long-lived NFSv4 connection can supply the reset half.\nAC:L - On 5.4.x/5.10.x xs_tcp_send_request() has no transport-\u003einet guard and xprt_sock_sendmsg() explicitly tolerates a NULL sock, so a stale flag plus one send on a torn-down transport is a deterministic oops; on 6.x the attacker controls both sides of the narrow window (callback traffic forces a send, RST forces the concurrent reset) and can retry on every reconnect.\nPR:N - The victim is the NFS client; a server does not authenticate to its clients, and the attacker needs no credentials or account on the target host \u2014 only the ability to answer RPCs on an existing mount or inject into its TCP connection.\nUI:N - No victim action is needed at exploitation time \u2014 an already-mounted NFSv4 share is a standing deployment condition, and the server drives the FSINFO refresh, callback traffic and connection reset on its own schedule.\nS:U - The NULL dereference occurs in the sunrpc transport code within the same kernel security authority; no VM, IOMMU or sandbox boundary is crossed.\nC:N - transport-\u003esock is exactly NULL and is dereferenced at a small fixed offset below mmap_min_addr; the fault aborts before any data is read, so nothing is disclosed.\nI:N - The access faults on an unmapped low address before any store completes \u2014 there is no attacker-controlled pointer, offset or value, hence no write primitive or data modification.\nA:H - A NULL pointer dereference in the RPC transmit path oopses the kernel while XPRT_LOCKED is held, permanently wedging the NFS mount and killing the rpciod/xprtiod worker; with panic_on_oops (common on embedded, automotive and appliance deployments) it is a full panic, and the server can repeat it on every reconnect."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
