CVE-2026-23198 KVM: Don't clobber irqfd routing type when deassigning irqfd

In the Linux kernel, the following vulnerability has been resolved: KVM: Don't clobber irqfd routing type when deassigning irqfd When deassigning a KVMIRQFD, don't clobber the irqfd's copy of the IRQ's routing entry as doing so breaks kvmarchirqbypassdelproducer on x86 and arm64, which explicitly...

CVE-2026-23198

CVE-2026-23198 relates to the Linux kernel KVM irqfd handling. The vulnerability arose when deassociating an IRQFD could clobber the irqfd’s copy of the IRQ’s routing entry, causing arch-specific code (e.g., kvm_arch_irq_bypass_del_producer on x86/arm64) to misinterpret routing as MSI. The fix ch...

CVE-2026-23029

The CVE-2026-23029 entry describes a memory-leak in the LoongArch KVM path of the Linux kernel. In kvm_ioctl_create_device(), kvm_device is allocated, but the kvm_device->destroy() path (kvm_eiointc_destroy()) does not free the allocated kvm_device struct, leading to a leak. Multiple sources (...

CVE-2026-23027

The provided reports describe a Linux kernel issue for LoongArch KVM: in kvm_ioctl_create_device(), memory is allocated for kvm_device, and the destroy() path (kvm_pch_pic_destroy()) did not free the allocated struct, causing a memory leak. The fix is to ensure kvm_pch_pic_destroy() frees the kvm...
