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

KVM: s390: Properly handle NULL pointer in dat cond set storage key()

Some callers pass NULL as oldkey. Calling page cond set storage key() will cause that NULL pointer to get dereferenced.

Fix by checking for NULL and assigning the pointer to a dummy local variable to avoid crashes.
