CVE-2022-50645 EDAC/i10nm: fix refcount leak in pci_get_dev_wrapper()

In the Linux kernel, the following vulnerability has been resolved: EDAC/i10nm: fix refcount leak in pcigetdevwrapper As the comment of pcigetdomainbusandslot says, it returns a PCI device with refcount incremented, so it doesn't need to call an extra pcidevget in pcigetdevwrapper, and the PCI...

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...
