  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: mvpp2: limit XDP frame size to the RX buffer\n\nmvpp2 has short and long BM pools, and short pool buffers can be smaller\nthan PAGE_SIZE. The XDP path nevertheless initializes every xdp_buff with\nPAGE_SIZE as frame size.\n\nXDP helpers use frame_sz to validate tail growth and to derive the hard\nend of the data area. Advertising PAGE_SIZE for short buffers can let\nbpf_xdp_adjust_tail() grow a packet past the real allocation, corrupting\nmemory or later tripping skb tailroom checks.\n\nInitialize the XDP buffer with bm_pool-\u003efrag_size so XDP tailroom matches\nthe actual buffer backing the packet.",
