CVE-2024-56600

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

net: inet6: do not leave a dangling sk pointer in inet6_create()

sock_init_data() attaches the allocated sk pointer to the provided sock object. If inet6_create() fails later, the sk object is released, but the sock object retains the dangling sk pointer, which may cause use-after-free later.

Clear the sock sk pointer on error.

This issue is considered to be a moderate impact flaw, it seems this the data leak is from TCP protocol stack on not of all kernel space.
