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...

CVE-2026-53215

CVE-2026-53215 affects the Linux kernel mvpp2 driver: the RX path could return a descriptor buffer to the hardware Buffer Manager after it had been handed to XDP or an skb, allowing DMA into memory no longer owned by the RX ring. Root cause is improper handling of RX buffers in mvpp2_rx_refill() ...
