What fixes it

  • 30335038d4e25cf017abb0562f4f4eace4f58f96LinuxCVE List

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

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().
