Title
NFSD: Prevent a potential integer overflow
Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSD: Prevent a potential integer overflow
If the tag length is >= U32_MAX - 3 then the "length + 4" addition
can result in an integer overflow. Address this by splitting the
decoding into several steps so that decode_cb_compound4res() does
not have to perform arithmetic on the unsafe length value.

"value": "AV:N - The vulnerable parser is in nfsd\u0027s NFSv4 callback client (fs/nfsd/nfs4callback.c), decoding a CB_COMPOUND4res reply received over TCP from a remote NFS peer. A malicious NFS client controls every byte of that reply, either via its v4.1+ backchannel or via the v4.0 callback address it itself supplied in SETCLIENTID.\nAC:L - The attacker deterministically sets the tag length field to exactly 0xFFFFFFFC and elicits a callback on demand (async COPY\u2192CB_OFFLOAD, blocking LOCK\u2192CB_NOTIFY_LOCK, or delegation conflict\u2192CB_RECALL); no race and no memory-grooming is required. The attempt can be repeated indefinitely, and each callback re-allocates the reply buffer at a different slab address, sweeping different +4 GiB targets until one faults.\nPR:N - In the standard sec=sys deployment NFS performs no cryptographic authentication \u2014 the client merely asserts a uid \u2014 so any host permitted by the export (commonly a whole subnet, VPC, or a wildcard) reaches this code with no verified credentials. EXCHANGE_ID/CREATE_SESSION require no export access at all, and the vulnerable decode runs before any CB_SEQUENCE session validation.\nUI:N - The attacker drives both halves of the exchange itself: it triggers the callback with its own ordinary NFS operations and then sends the malformed reply. No action by an administrator or any other client is needed.\nS:U - The out-of-bounds read and the resulting fault are confined to the kernel\u0027s own memory and the rpciod worker context, all within a single security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The dereference lands roughly 4 GiB away from the slab-allocated receive buffer, reading kernel memory entirely unrelated to the RPC object \u2014 this is a wild read, not one strictly bounded to a few bytes past its object. When the target is unmapped the resulting oops dumps registers, kernel addresses, and a stack trace to the log, defeating KASLR.\nI:N - The bug is purely a read; the only write is `hdr-\u003enops`, an in-bounds store to a stack-local struct that every caller leaves unused. No kernel structure is corrupted and the attacker gains no write primitive or control-flow influence.\nA:H - A 4 GiB displacement into the direct map frequently hits an unmapped hole, faulting on a kernel address inside the rpciod workqueue \u2014 a panic under panic_on_oops, otherwise a dead RPC worker that wedges the callback machinery and leaks RPC state. The remote attacker can repeat this at will until it crashes."

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.
