How to fix?

Upgrade SLES:15.0 kernel-vanilla-base to version 4.12.14-150.58.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-vanilla-base package and not the kernel-vanilla-base package as distributed by SLES. See How to fix? for SLES:15.0 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.
