In the Linux kernel, the following vulnerability has been resolved: ksmbd: run set info with opener credentials SMB2 SETINFO handlers call path-based VFS helpers after checking the access mask granted to the SMB handle. Those helpers perform their owner, inode permission and LSM checks using the current ksmbd worker credentials. Run the complete SETINFO dispatch with the credentials captured when the handle was opened. This also removes the separate security information credential setup and keeps all SETINFO classes under one credential scope. Direct overridecreds() is used because it can nest with the request credential overrides already used by rename and link helpers.
