Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> s390/dasd: Fix invalid dereferencing of indirect CCW data pointer<br /> <br /> Fix invalid dereferencing of indirect CCW data pointer in<br /> dasd_eckd_dump_sense() that leads to a kernel panic in error cases.<br /> <br /> When using indirect addressing for DASD CCWs (IDAW) the CCW CDA pointer<br /> does not contain the data address itself but a pointer to the IDAL.<br /> This needs to be translated from physical to virtual as well before<br /> using it.<br /> <br /> This dereferencing is also used for dasd_page_cache and also fixed<br /> although it is very unlikely that this code path ever gets used.
