Description OSIDB Bzimport 2026-10-06 09:10:55 UTC 
In the Linux kernel, the following vulnerability has been resolved:

nfsd: fix handling of NFSEXP_PNFS in the netlink codepath

The rework of how block layouts were checked moved the check for
NFSEXP_PNFS out of nfsd4_setup_layout_type() and into the callers. That
patch didn't account for the new call in nfsd4_setup_layout_type().
