CVE-2026-80865

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

bpf: Add missing access ok call to copy user syms

As reported by sashiko we use get user without prior access ok call on the user space pointer. Adding the missing call for the whole pointer array.

Plus removing the err check in the error path, because it's not needed and also we can return -ENOMEM directly from the first kvmalloc array fail path.
