net: inet: do not leave a dangling sk pointer in inet_create()
In the Linux kernel, the following vulnerability has been resolved: net: inet: do not leave a dangling sk pointer in inet_create() sock_init_data() attaches the allocated sk object to the provided sock object. If inet_create() fails later, the sk object is freed, but the sock object retains the dangling pointer, which may create use-after-free later. Clear the sk pointer in the sock object on error.
