CVE-2026-74515

In the Linux kernel, the following vulnerability has been resolved: KVM: s390: pci: Reject adapter interrupt forwarding if already enabled The MPCIFC instruction doesn't allow registering adapter interrupts without first unregistering. So reject any request to enable interrupt forwarding if its...

CVE-2026-74515 KVM: s390: pci: Reject adapter interrupt forwarding if already enabled

In the Linux kernel, the following vulnerability has been resolved: KVM: s390: pci: Reject adapter interrupt forwarding if already enabled The MPCIFC instruction doesn't allow registering adapter interrupts without first unregistering. So reject any request to enable interrupt forwarding if its...

CVE-2026-74515

CVE-2026-74515 is a Linux kernel vulnerability affecting KVM on s390 where the MPCIFC instruction may register adapter interrupts without proper unregistering. The fix rejects enabling interrupt forwarding if it is already enabled for a zPCI device, preventing overwriting and leakage of resources...

CVE-2026-52968

In the Linux kernel, the following vulnerability has been resolved: KVM: s390: pci: fix GAIT table indexing due to double-scaling pointer arithmetic kvms390pciaifenable, kvms390pciaifdisable, and aenhostforward index the GAIT by manually multiplying the index with sizeofstruct zpcigaite. Since...

CVE-2026-52968

CVE-2026-52968 affects the Linux kernel KVM on s390. The root cause is double-scaling the GAIT table index: code in kvm_s390_pci_aif_enable(), kvm_s390_pci_aif_disable(), and aen_host_forward() multiplies the GAIT index by sizeof(struct zpci_gaite) even though gait is already a pointer to struct ...

CVE-2025-39939

The CVE-2025-39939 issue affects the Linux kernel (iommu/s390) where zpci_get_iommu_ctrs() could read a bad address for identity-domain devices, causing memory corruption. The root cause is that identity domains are not backed by an s390_domain, leading to an invalid to_s390_domain() result and o...
