CVE-2025-38430
In the Linux kernel, the following vulnerability has been resolved: nfsd: nfsd4_spo_must_allow() must check this is a v4 compound request If the request being processed is not a v4 compound request, then examining the cstate can have undefined results.
Does this matter?
Lower severity and a low EPSS score (0.50%). Track it; it rarely justifies an emergency change on its own.
