CVE-2026-45887

Description

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

af_unix: Fix memleak of newsk in unix_stream_connect().

When prepare_peercred() fails in unix_stream_connect(), unix_release_sock() is not called for newsk, and the memory is leaked.

Let's move prepare_peercred() before unix_create1().
