CVE-2022-50645

The CVE-2022-50645 issue involves a refcount leak in the Linux kernel’s EDAC/i10nm path. Specifically, pci_get_dev_wrapper() could mishandle a PCI device by not accounting for the fact that pci_get_domain_bus_and_slot() returns a device with an incremented refcount, leading to a potential leak if...
