Descriptions

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

s390/dasd: Fix invalid dereferencing of indirect CCW data pointer

Fix invalid dereferencing of indirect CCW data pointer in
dasd_eckd_dump_sense() that leads to a kernel panic in error cases.

When using indirect addressing for DASD CCWs (IDAW) the CCW CDA pointer
does not contain the data address itself but a pointer to the IDAL.
This needs to be translated from physical to virtual as well before
using it.

This dereferencing is also used for dasd_page_cache and also fixed
although it is very unlikely that this code path ever gets used.
