CVE-2026-23204

CVE-2026-23204 affects the Linux kernel net/sched cls_u32. The root cause is that skb_header_pointer() does not fully validate negative @offset values, enabling a slab-out-of-bounds condition in u32_classify() (reported as BUG: KASAN). The fix replaces skb_header_pointer() with skb_header_pointer...
