  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nKVM: s390: pci: fix GAIT table indexing due to double-scaling pointer arithmetic\n\nkvm_s390_pci_aif_enable(), kvm_s390_pci_aif_disable(), and\naen_host_forward() index the GAIT by manually multiplying the index\nwith sizeof(struct zpci_gaite).\n\nSince aift->gait is already a struct zpci_gaite pointer, this\ndouble-scales the offset, accessing element aisb*16 instead of aisb.\n\nThis causes out-of-bounds accesses when aisb >= 32 (with\nZPCI_NR_DEVICES=512)\n\nFix by removing the erroneous sizeof multiplication.",
