CVE-2026-53216

The CVE-2026-53216 issue affects the Linux kernel mvpp2 XDP path. Short pool buffers can be smaller than PAGE_SIZE, yet XDP initially sets every xdp_buff frame size to PAGE_SIZE. The XDP helpers then use frame_sz to validate tail growth, which, with an oversized frame, can allow bpf_xdp_adjust_ta...
