Description
In the Linux kernel, the following vulnerability has been resolved:
KVM: s390: pci: Fix NULL dereference on AIBV allocation failure
The airq_iv_create() can return NULL on failure, but the return value was never checked. If it fails, zdev->aibv will be NULL and fail when dereferenced in kvm_zpci_set_airq(). Add a NULL check and free the previously allocated AISB bit and zdev->aisb on failure.
