CVE-2026-68454

In the Linux kernel KVM s390 PCI implementation, CVE-2026-68454 arises from improper handling when a guest registers IRQs without a summary bit: the GAITE stores a invalid address (virt_to_phys(page_address(NULL))) instead of 0 for the guest AISB. Root cause is memory address handling in this pat...
