Details

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

KVM: s390: fix validity interception issue when gisa is switched off

We might run into a SIE validity if gisa has been disabled either via using kernel parameter "kvm.usegisa=0" or by setting the related sysfs attribute to N (echo N >/sys/module/kvm/parameters/usegisa).

The validity is caused by an invalid value in the SIE control block's gisa designation. That happens because we pass the uninitialized gisa origin to virttophys() before writing it to the gisa designation.

To fix this we return 0 in kvms390getgisadesc() if the origin is 0. kvms390getgisadesc() is used to determine which gisa designation to set in the SIE control block. A value of 0 in the gisa designation disables gisa usage.

The issue surfaces in the host kernel with the following kernel message as soon a new kvm guest start is attemted.
