How to fix?

This issue was patched in RHSA-2021:1578.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-zfcpdump-devel package and not the kernel-zfcpdump-devel package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the current umask is not considered.
