kernel: af_unix: Drop all SCM attributes for SOCKMAP

A flaw was found in the Linux kernel's afunix component, specifically within its SOCKMAP feature. This vulnerability stems from the kernel's improper handling of Socket Control Message SCM attributes when data is passed to the SOCKMAP layer. This can lead to a use-after-free condition, which may...
