Bandit HTTP/2 Frame Size Limit Bypass via Late Buffer Check Enables Memory Exhaustion

Summary Bandit's HTTP/2 parser checks frame size after it has already buffered the full body, instead of when it sees the 9-byte header. A peer can announce a 16 MiB frame on a connection that agreed to 16 KiB frames and the server will silently buffer up to 1024× the agreed budget per connection...

CVE-2026-42788 HTTP/2 frame size limit checked after body is buffered in bandit

Allocation of Resources Without Limits or Throttling vulnerability in mtrudel bandit allows unauthenticated memory exhaustion via oversized HTTP/2 frames. 'Elixir.Bandit.HTTP2.Frame':deserialize/2 in lib/bandit/http2/frame.ex checks the SETTINGSMAXFRAMESIZE limit only after pattern-matching...

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...
