Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
s390/mm: Add NULL pointer check to crst_table_free() base_crst_free()<br />
<br />
crst_table_free() used to work with NULL pointers before the conversion<br />
to ptdescs. Since crst_table_free() can be called with a NULL pointer<br />
(error handling in crst_table_upgrade() add an explicit check.<br />
<br />
Also add the same check to base_crst_free() for consistency reasons.<br />
<br />
In real life this should not happen, since order two GFP_KERNEL<br />
allocations will not fail, unless FAIL_PAGE_ALLOC is enabled and used.
