Linux hwe edge: In the Linux kernel, the following vulnerability has been resolved: KVM: s390: pci: fix GAIT table indexing due to double-scaling pointer arithmetic… (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 kvm_s390_pci_aif_enable(), kvm_s390_pci_aif_disable(), and aen_host_forward() index the GAIT by manually multiplying the index with sizeof(struct zpci_gaite). Since aift->gait is already a struct zpci_gaite pointer, this double-scales the offset, accessing element aisb*16 instead of aisb. This causes out-of-bounds accesses when aisb >= 32 (with ZPCI_NR_DEVICES=512) Fix by removing the erroneous sizeof multiplication.
