Medium [CVE-2026-68454] Fix handling of AIF enable without AISB
CVE-2026-68454Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: KVM: s390: pci: Fix handling of AIF enable without AISB When a guest seeks to register IRQs without a summary bit specified, ensure that the associated GAITE then stores 0 for the guest AISB location instead of virt_to_phys(page_address(NULL)). A flaw was found in the KVM (Kernel-based Virtual Machine) subsystem of the Linux kernel, affecting the s390 PCI implementation. When a guest operating system registers interrupt requests (IRQs) without a specific summary bit, the system incorrectly stores an invalid memory address. This improper handling of memory addresses can lead to system instability, potentially resulting in a denial of service for the host system. Red Hat severity: Moderate — CVSS 5.5…
