kvm s390

About this tag
The kvm s390 tag covers discussions about the Kernel-based Virtual Machine (KVM) implementation on IBM Z and LinuxONE s390 systems. Recent content focuses on security vulnerabilities and patches, such as CVE-2024-43819, which addresses a null-pointer dereference in the s390 KVM code that could lead to a denial-of-service. The fix involves rejecting certain memory region ioctls for ucontrol VMs and directing memory management to the s390-specific KVM_S390_UCAS_MAP and KVM_S390_UCAS_UNMAP interfaces. This tag is relevant for administrators and developers working with KVM on s390 hardware, particularly those concerned with stability and security patches.

    KVM s390 CVE-2024-43819 Patch Prevents Memory Region DoS

    A small, surgical kernel change has been credited with closing a potentially disruptive hole in the Linux KVM stack: CVE-2024-43819 addresses a defect in the s390 KVM implementation that could lead to a null-pointer dereference when userland memory-region ioctls are used against ucontrol VMs...
