In the Linux kernel, the following vulnerability has been resolved:
nfsd: nfsd4_spo_must_allow() must check this is a v4 compound request

examining the cstate can have undefined results.
This patch adds a check that the rpc procedure being executed
(rq_procinfo) is the NFSPROC4_COMPOUND procedure.
