CVE-2026-89453

CVE-2026-89453 is a PCI device reference count leak in the Linux kernel's iommu/amd subsystem. The function iommu_call_iopf_notifier() calls pci_get_domain_bus_and_slot() which increments the device's reference count, but neither the successful iommu_report_device_fault() path nor the abort path ...

CVE-2026-89454

CVE-2026-89454 affects the Linux kernel in the PCI plda driver. The function plda_init_interrupts() initializes IRQ domains and creates IRQ mappings but fails to unwind them when a later step fails. Specifically, if platform_get_irq() or irq_create_mapping() fails, the domains are never deinitial...

CVE-2026-89452

CVE-2026-89452 affects the iommu/msm driver in the Linux kernel. The root cause is an improper error-handling path in msm_iommu_probe(): when iommu_device_sysfs_add() or iommu_device_register() fails, the IOMMU object is left in the global qcom_iommu_devices list after its devm-managed memory has...
