"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: zero the FS_OBJECT_ID_INFORMATION buffer before filling it in\n\nsmb2_get_info_filesystem() reports 64 bytes for FS_OBJECT_ID_INFORMATION,\nthat is the whole of struct object_id_info, but writes only 46 of them:\n\n - objid[] is 16 bytes, and when the volume UUID is not available only\n sizeof(stfs.f_fsid) (8) bytes are copied into it;\n - extended_info.version_string[] is STRING_LENGTH (28) bytes, and only\n strlen(\"1.1.0\") (5) bytes are copied into it.\n\nThe response buffer is zeroed on allocation (kvzalloc() in\nsmb2_allocate_rsp_buf()), so for a standalone request the remaining 31\nbytes are zero. In a compound request they need not be. The offset of\nthe next response is advanced by the length pinned for the previous one,\nso if a preceding command wrote its reply into the buffer and then\nfailed, smb2_set_err_rsp() pins only the short error response and the\nnext reply lands inside the area that has already been written. Only\nthe header is cleared there:\n\n\tmemset((char *)rsp_hdr, 0, sizeof(struct smb2_hdr) + 2);\n\nThe client then receives up to 31 bytes of a response it was not meant\nto see, including one that failed with an access denied error.\n\nClear the structure before filling it in. As a side effect\nversion_string is now NUL terminated."
