No local access is required.\nAC:L - On any export with an explicit sec= list, an RPC using a non-listed flavor (AUTH_SYS/AUTH_NULL) deterministically reaches the type-confused read, and for lockd the out-of-bounds access past the smaller rq_resp allocation is unconditional. The attacker can itself prime the shared per-thread buffer with prior NFSv4.1 compounds and retry indefinitely, so it controls both sides of the stale-data condition.\nPR:N - The path is hit precisely with AUTH_SYS/AUTH_NULL credentials, i.e. before any authentication succeeds \u2014 the bug lives in the code that decides whether authentication is required at all. Exports secured with sec=krb5 are routinely exported to wide host lists (`*`), so no credentials on the target are needed.\nUI:N - Exploitation requires only sending crafted NFSv3/NLM RPCs to the server; no administrator or client-side user action is involved.\nS:U - The type confusion, out-of-bounds reads and the bypassed authorization decision all occur within the kernel\u0027s own security authority; no VM, IOMMU or sandbox boundary is crossed.\nC:H - A stale `spo_must_allowed` byte makes check_security_flavor() return nfs_ok, bypassing the export\u0027s Kerberos requirement and exposing all file contents on that export to an unauthenticated client; additionally the dangling `cstate-\u003eclp` and `test_bit()` with an uncontrolled 32-bit index give wide out-of-bounds/use-after-free kernel reads.\nI:H - The same sec= bypass yields write access to a read-write Kerberos-protected export for an unauthenticated AUTH_SYS client, and the code also writes `cstate-\u003espo_must_allowed` back into a mis-typed response buffer, corrupting whatever NFSv3/NLM structure occupies that offset.\nA:H - `cstate-\u003eclp` is an uninitialized, stale or out-of-bounds value used directly as a `struct nfs4_client *` and dereferenced (including a strcmp of `cl_cred.cr_raw_principal` and a bit test at an arbitrary 32-bit offset), which readily faults and oopses the nfsd/lockd thread, and the request can be repeated at will."
