CVE-2024-50256 is a Linux kernel netfilter vulnerability in the IPv6 rejection path, specifically nf_send_reset6() in nf_reject_ipv6. When a network device has a zero hard_header_len, the function can reserve insufficient link-layer header space and subsequently attempt to push an Ethernet header. This causes an sk_buff underwrite (skb_under_panic) and triggers a kernel BUG. The upstream correction uses LL_MAX_HEADER to reserve adequate link-layer header space.
