CVE-2026-68454

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...

CVE-2026-52968

CVE-2026-52968 affects the Linux kernel KVM on s390. The root cause is double-scaling the GAIT table index: code in kvm_s390_pci_aif_enable(), kvm_s390_pci_aif_disable(), and aen_host_forward() multiplies the GAIT index by sizeof(struct zpci_gaite) even though gait is already a pointer to struct ...

CVE-2025-68310

In the Linux kernel, the following vulnerability has been resolved: s390/pci: Avoid deadlock between PCI error recovery and mlx5 crdump Do not block PCI config accesses through pcicfgaccesslock when executing the s390 variant of PCI error recovery: Acquire just devicelock instead of pcidevlock as...

CVE-2025-68310

CVE-2025-68310 : Linux kernel fix for a deadlock between PCI error recovery and mlx5 crdump on s390. The patch avoids blocking PCI config accesses by PCI error recovery code by acquiring only device_lock() (not pci_dev_lock()), preventing hangs in mlx5_health_unload and crdump collection when PCI...
