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-2026-80974

CVE-2026-80974 affects the Linux kernel in the mfd sm501 driver. The memory allocated for struct sm501_devdata in sm501_pci_probe() and sm501_plat_probe() is not freed by the corresponding remove functions, resulting in a memory leak when the device is removed. The fix adds a kfree() call in sm50...

CVE-2026-80940

In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: pci: fix resource leak on failed NAPI setup rtwpciprobe allocates PCI resources through rtwpcisetupresource before it sets up NAPI. If rtwpcinapiinit fails, the error path jumps straight to errpcideclaim and skips...

CVE-2026-80940

CVE-2026-80940 is a resource leak in the Linux kernel's rtw88 PCI Wi-Fi driver. When rtw_pci_napi_init() fails during device probing, the error path jumps to err_pci_declaim without calling rtw_pci_destroy(), leaving PCI resources allocated by rtw_pci_setup_resource() leaked. The fix adds a dedic...

CVE-2026-80939

CVE-2026-80939 affects the Linux kernel rtw89 PCI WiFi driver on arm64 platforms. The root cause is a missing .shutdown callback: during warm reboot the kernel invokes device_shutdown() but not .remove(), so the rfkill polling workqueue continues issuing MMIO reads to the PCI device after the PCI...
