Local kernel memory exhaustion via leaked file references

Resource leak in the Linux Kernel fremovexattr syscall allows local users to exhaust kernel memory through an unreadable name pointer. When strncpy_from_user fails, the error path returns after fdget without calling fdput, permanently pinning a file and related kernel objects. Exploitation requires an unprivileged local user in a multithreaded process and repeated slow-path fdget calls, resulting in denial of service as kernel memory is consumed.
