Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A NULL dereference occurs in the KVM s390 PCI component when the
airq iv create() function fails to allocate an AIBV (Airq Interrupt Vector) and returns NULL. Because the return value was not checked, the zdev->aibv variable remains NULL, leading to a system failure when it is subsequently dereferenced within the kvm zpci set airq() function.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
