CVE-2023-54155

The CVE relates to the Linux kernel net/xdp path. Root cause: a previous check enforcing xdp.frame_sz > PAGE_SIZE was removed in the context of allowing bpf_xdp_adjust_tail() to grow packet size, after xdp_init_buff() was introduced. This can allow excessive frame sizes (e.g., xdp->frame_sz...
