"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: esp: fix bad handling of pages from page_pool\n\nWhen the skb is reorganized during esp_output (!esp->inline), the pages\ncoming from the original skb fragments are supposed to be released back\nto the system through put_page. But if the skb fragment pages are\noriginating from a page_pool, calling put_page on them will trigger a\npage_pool leak which will eventually result in a crash.\n\nThis leak can be easily observed when using CONFIG_DEBUG_VM and doing\nipsec + gre (non offloaded) forwarding:\n\n BUG: Bad page state in process ksoftirqd/16 pfn:1451b6\n page:00000000de2b8d32 refcount:0 mapcount:0 mapping:0000000000000000 index:0x1451b6000 pfn:0x1451b6\n flags: 0x200000000000000(node=0|zone=2)\n page_type: 0xffffffff()\n raw: 0200000000000000 dead000000000040 ffff88810d23c000 0000000000000000\n raw: 00000001451b6000 0000000000000001 00000000ffffffff 0000000000000000\n page dumped because: page_pool leak\n Modules linked in: ip_gre gre mlx5_ib mlx5_core xt_conntrack xt_MASQUERADE nf_conntrack_netlink nfnetlink iptable_nat nf_nat xt_addrtype br_netfilter rpcrdma rdma_ucm ib_iser libiscsi scsi_transport_iscsi ib_umad rdma_cm ib_ipoib iw_cm ib_cm ib_uverbs ib_core overlay zram zsmalloc fuse [last unloaded: mlx5_core]\n CPU: 16 PID: 96 Comm: ksoftirqd/16 Not tainted 6.8.0-rc4+ #22\n Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014\n Call Trace:\n <TASK>\n dump_stack_lvl+0x36/0x50\n bad_page+0x70/0xf0\n free_unref_page_prepare+0x27a/0x460\n free_unref_page+0x38/0x120\n esp_ssg_unref.isra.0+0x15f/0x200\n esp_output_tail+0x66d/0x780\n esp_xmit+0x2c5/0x360\n validate_xmit_xfrm+0x313/0x370\n ? validate_xmit_skb+0x1d/0x330\n validate_xmit_skb_list+0x4c/0x70\n sch_direct_xmit+0x23e/0x350\n __dev_queue_xmit+0x337/0xba0\n ? nf_hook_slow+0x3f/0xd0\n ip_finish_output2+0x25e/0x580\n iptunnel_xmit+0x19b/0x240\n ip_tunnel_xmit+0x5fb/0xb60\n ipgre_xmit+0x14d/0x280 [ip_gre]\n dev_hard_start_xmit+0xc3/0x1c0\n __dev_queue_xmit+0x208/0xba0\n ? nf_hook_slow+0x3f/0xd0\n ip_finish_output2+0x1ca/0x580\n ip_sublist_rcv_finish+0x32/0x40\n ip_sublist_rcv+0x1b2/0x1f0\n ? ip_rcv_finish_core.constprop.0+0x460/0x460\n ip_list_rcv+0x103/0x130\n __netif_receive_skb_list_core+0x181/0x1e0\n netif_receive_skb_list_internal+0x1b3/0x2c0\n napi_gro_receive+0xc8/0x200\n gro_cell_poll+0x52/0x90\n __napi_poll+0x25/0x1a0\n net_rx_action+0x28e/0x300\n __do_softirq+0xc3/0x276\n ? sort_range+0x20/0x20\n run_ksoftirqd+0x1e/0x30\n smpboot_thread_fn+0xa6/0x130\n kthread+0xcd/0x100\n ? kthread_complete_and_exit+0x20/0x20\n ret_from_fork+0x31/0x50\n ? kthread_complete_and_exit+0x20/0x20\n ret_from_fork_asm+0x11/0x20\n </TASK>\n\nThe suggested fix is to introduce a new wrapper (skb_page_unref) that\ncovers page refcounting for page_pool pages as well."
