CVE-2021-47425
"ACPI I2C Linux Kernel Resource Leaking Denial of Service"
Description
In the Linux kernel, the following vulnerability has been resolved: i2c: acpi: fix resource leak in reconfiguration device addition acpi_i2c_find_adapter_by_handle() calls bus_find_device() which takes a reference on the adapter which is never released which will result in a reference count leak and render the adapter unremovable. Make sure to put the adapter after creating the client in the same manner that we do for OF. [wsa: fixed title]
