In the Linux kernel, the following vulnerability has been resolved:

i2c: core: fix adapter deregistration race

Adapters can be looked up by their id using i2c_get_adapter() which takes a reference to the embedded struct device.

Remove the adapter from the IDR before tearing it down during deregistration (and on registration failure) to make sure its resources are not accessed after having been freed (e.g. the device name).
