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

scsi: csiostor: Fix dereference of null pointer rn

The error exit path when rn is NULL ends up deferencing the null pointer rn via the use of the macro CSIO INC STATS. Fix this by adding a new error return path label after the use of the macro to avoid the deference.
