"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: mana: Fix RX buf alloc_size alignment and atomic op panic\n\nThe MANA driver's RX buffer alloc_size is passed into napi_build_skb() to\ncreate SKB. skb_shinfo(skb) is located at the end of skb, and its alignment\nis affected by the alloc_size passed into napi_build_skb(). The size needs\nto be aligned properly for better performance and atomic operations.\nOtherwise, on ARM64 CPU, for certain MTU settings like 4000, atomic\noperations may panic on the skb_shinfo(skb)->dataref due to alignment fault.\n\nTo fix this bug, add proper alignment to the alloc_size calculation.\n\nSample panic info:\n[ 253.298819] Unable to handle kernel paging request at virtual address ffff000129ba5cce\n[ 253.300900] Mem abort info:\n[ 253.301760] ESR = 0x0000000096000021\n[ 253.302825] EC = 0x25: DABT (current EL), IL = 32 bits\n[ 253.304268] SET = 0, FnV = 0\n[ 253.305172] EA = 0, S1PTW = 0\n[ 253.306103] FSC = 0x21: alignment fault\nCall trace:\n __skb_clone+0xfc/0x198\n skb_clone+0x78/0xe0\n raw6_local_deliver+0xfc/0x228\n ip6_protocol_deliver_rcu+0x80/0x500\n ip6_input_finish+0x48/0x80\n ip6_input+0x48/0xc0\n ip6_sublist_rcv_finish+0x50/0x78\n ip6_sublist_rcv+0x1cc/0x2b8\n ipv6_list_rcv+0x100/0x150\n __netif_receive_skb_list_core+0x180/0x220\n netif_receive_skb_list_internal+0x198/0x2a8\n __napi_poll+0x138/0x250\n net_rx_action+0x148/0x330\n handle_softirqs+0x12c/0x3a0"
