A kernel Null reference and crash cuased by SMB command #548

Closed PoleTIC closed 2 years ago

PoleTIC commented 2 years ago

A Null pointer reference in kernel has been observed when using the smbclient "volume" command causing a kernel crash. Tested on ksmbd (3.3.7) as follows: $ smbclient //192.168.2.1/ipc$ $ smb: > volume

There is any fix intended to this issue ?

Regards

At least, you need to share kernel oops backtrace.

linkinjeon@linkinjeon-Z10PA-D8-Series:~$ smbclient //172.30.1.20/ipc$ Enter WORKGROUP\linkinjeon's password: Try "help" to get a list of possible commands. smb: > volume Error NT_STATUS_INVALID_PARAMETER getting volume info smb: >

I will test on the latest version and put the backtrace if the issue is still there. Thanks
