CVE-2024-56601 Information

Description

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.
