Linux Kernel proc_readdir_de() Use-After-Free Local Privilege Escalation

A local privilege escalation vulnerability exists in the Linux Kernel versions ~3.14+ through 6.18-rc5 due to a use-after-free in the proc_readdir_de() function, where a concurrent traversal can dereference a freed entry's fields during network device unregistration, leading to privilege escalation via modprobe_path overwrite.
