CVE-2026-43040 POC (Proof-of-Concept)

In the Linux kernel, the following vulnerability has been resolved:
net: ipv6: ndisc: fix ndisc_ra_useropt to initialize nduseropt_padX fields to zero to prevent an info-leak
When processing Router Advertisements with user options the kernel
builds an RTM_NEWNDUSEROPT netlink message. The nduseroptmsg struct
has three padding fields that are never zeroed and can leak kernel data
The fix is simple, just zeroes the padding fields.
