Details

In the Linux kernel, the following vulnerability has been resolved: scsi: target: Fix WRITESAME No Data Buffer crash In newer version of the SBC specs, we have a NDOB bit that indicates there is no data buffer that gets written out. If this bit is set using commands like "sgwritesame --ndob" we will crash in targetcoreiblock/file's executewritesame handlers when we go to access the secmd->tdatasg because its NULL. This patch adds a check for the NDOB bit in the common WRITE SAME code because we don't support it. And, it adds a check for zero SG elements in each handler in case the initiator tries to send a normal WRITE SAME with no data buffer.
