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. CREATE(Triage):(User=admin) [CVE-2020-24394|https://nvd.nist.gov/vuln/detail/CVE-2020-24394]
