  "details": "In the Linux kernel, the following vulnerability has been resolved:  ksmbd: initialize FileSystemControlFlags in FS_CONTROL_INFORMATION  smb2_get_info_filesystem() reports 48 bytes for FS_CONTROL_INFORMATION, that is the whole of struct smb2_fs_control_info, but never assigns FileSystemControlFlags.  Those four bytes go to the client as they are found in the response buffer.  The buffer is zeroed on allocation, so a standalone request leaks nothing.  A compound request can leak: the offset of the next response is advanced by the length pinned for the previous one, so a reply that was written into the buffer and then dropped in favour of the short error response of smb2_set_err_rsp() stays there, and the next reply is laid over it with only the header cleared.  ksmbd does not implement quota tracking, so report no control flags.",
