Details

In the Linux kernel, the following vulnerability has been resolved:

ksmbd: validate session id and tree id in compound request

smb2_get_msg() in smb2getksmbdtcon() and smb2checkusersession() will always return the first request smb2 header in a compound request. if SMB2_TREE_CONNECT_HE is the first command in compound request, will return 0, i.e. The tree id check is skipped.
