CVE-2022-49219

CVE-2022-49219 concerns a memory-leak in the Linux kernel VFIO PCI driver during D3hot↔D0 transitions. If vfio_pci_core_device::needs_pm_restore is set, the current PCI state is saved in pm_save on D0→D3hot and would be restored on D3hot→D0. The code uses pci_store_saved_state() to save state and...
