CVE-2022-50337
In the Linux kernel, the following vulnerability has been resolved: ocxl: fix pci device refcount leak when calling get_function_0() get_function_0() calls pci_get_domain_bus_and_slot(), as comment says, it returns a pci device with refcount increment,…
Does this matter?
Lower severity and a low EPSS score (0.16%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel, the following vulnerability has been resolved: ocxl: fix pci device refcount leak when calling get_function_0() get_function_0() calls pci_get_domain_bus_and_slot(), as comment says, it returns a pci device with refcount increment, so after using it, pci_dev_put() needs be called. Get the device reference when get_function_0() is not called, so pci_dev_put() can be called in the error path and callers unconditionally. And add comment above get_dvsec_vendor0() to tell callers to call pci_dev_put().
