CVE-2026-44433

CVE-2026-44433 concerns the Quicly QUIC implementation (used with H2O HTTP server). Before commit 8b178e6, an adversarial peer could send a STREAM frame with a single byte at the largest permitted offset to obtain additional flow control credit, potentially causing a denial of service. If the app...

CVE-2026-44433 Quicly is vulnerable to memory exhaustion

Quicly is an IETF QUIC protocol implementation intended primarily for use within the H2O HTTP server. Prior to commit 8b178e6, an adversarial peer could send a STREAM frame carrying just one byte at the largest offset being permitted to obtain additional flow control credit, which under certain...

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...
