Description
In the Linux kernel, the following vulnerability has been resolved: s390/dasd: Fix potential NULL pointer dereference dasd_release_space() checks the implementation of the is_ese() discipline function before calling it to determine if a given device is an ESE DASD. The current usage of the logical AND operator will lead to a NULL pointer dereference as the function is called even if the function pointer is NULL. Fix this by using the logical OR operator.
