The vulnerability is fixed in the Linux kernel commits f76017a7663c4ce5e379f8a8d39f032bdb1fd865 and 30335038d4e25cf017abb0562f4f4eace4f58f96. Users should update their Linux kernel to versions including these fixes. No additional mitigation guidance is provided.
Description
A vulnerability in the Linux kernel's nfsd component related to the handling of NFSEXP_PNFS in the netlink codepath has been fixed. The issue arose due to a rework that moved the check for NFSEXP_PNFS out of nfsd4_setup_layout_type() into its callers, but did not account for a new call within nfsd4_setup_layout_type(). This flaw has been addressed in specific commits.
