Description
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.
Weaknesses (CWE)
- CWE-732 — Incorrect Permission Assignment for Critical Resource
