Details

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

misc: ocxl: fix possible double free in ocxlfileregister_afu

inforelease() will be called in deviceunregister() when info->dev's reference count is 0. So there is no need to call ocxlafuput() and kfree() again.

Fix this by adding freeminor() and return to errunregister error path.
