CVE-2026-98250: nfsd: fix handling of NFSEXP_PNFS in the netlink codepath

Published Oct 6, 2026

Updated

In the Linux kernel, the following vulnerability has been resolved:

nfsd: fix handling of NFSEXPPNFS in the netlink codepath

The rework of how block layouts were checked moved the check for NFSEXPPNFS out of nfsd4setuplayouttype() and into the callers. That patch didn't account for the new call in nfsd4setuplayouttype().

Frequently Asked Questions

Can this information determine whether a specific kernel release is affected?

No affected kernel version range is provided. The supplied stable-tree references identify fixes, but the data does not map those commits to released kernel versions.

Does the available information establish an attacker’s prerequisites or whether default configurations are affected?

No. The data identifies the NFS server netlink path and NFSEXP_PNFS handling, but does not state required privileges, exposure conditions, exploitability, or default configuration impact.
