  "details": "In the Linux kernel, the following vulnerability has been resolved:  scsi: libiscsi: Fix stale-data leak into the SCSI sense buffer  iscsi_scsi_cmd_rsp() copies the sense data of a SCSI Response from the target-supplied data segment.  The segment carries a 2-byte sense length followed by the sense bytes, so it must hold 2 + senselen bytes, but the bounds check only requires datalen \u003e= senselen:  \tsenselen = get_unaligned_be16(data); \tif (datalen \u003c senselen) \t\tgoto invalid_datalen; \tmemcpy(sc-\u003esense_buffer, data + 2, \t       min_t(uint16_t, senselen, SCSI_SENSE_BUFFERSIZE));  A target that returns a SCSI Response whose datalen equals senselen (with senselen \u003c= SCSI_SENSE_BUFFERSIZE) makes the memcpy() from data + 2 read up to two bytes past the received data.  Those bytes are stale conn-\u003edata contents and end up in the command's sense buffer, which is returned to userspace.  Account for the 2-byte sense length prefix in the check.",
