Title
netfilter: ctnetlink: fix use-after-free in ctnetlink_dump_exp_ct()
Summary
In the Linux kernel, the following vulnerability has been resolved: netfilter: ctnetlink: fix use-after-free in ctnetlink_dump_exp_ct() ctnetlink_dump_exp_ct() stores a conntrack pointer in cb->data for the netlink dump callback ctnetlink_exp_ct_dump_table(), but drops the conntrack reference immediately after netlink_dump_start(). When the dump spans multiple rounds, the second recvmsg() triggers the dump callback which dereferences the now-freed conntrack via nfct_help(ct), leading to a use-after-free on ct->ext. The bug is that the netlink_dump_control has no .start or .done callbacks to manage the conntrack reference across dump rounds. Other dump functions in the same file (e.g. ctnetlink_get_conntrack) properly use .start/.done callbacks for this purpose. Fix this by adding .start and .done callbacks that hold and release the conntrack reference for the duration of the dump, and move the nfct_help() call after the cb->args[0] early-return check in the dump callback to avoid dereferencing ct->ext unnecessarily.

When the\\ndump spans multiple rounds, the second recvmsg() triggers the dump\\ncallback which dereferences the now-freed conntrack via nfct_help(ct),\\nleading to a use-after-free on ct-\u003eext.\\n\\nThe bug is that the netlink_dump_control has no .start or .done\\ncallbacks to manage the conntrack reference across dump rounds.  Other\\ndump functions in the same file (e.g. ctnetlink_get_conntrack) properly\\nuse .start/.done callbacks for this purpose.\\n\\nFix this by adding .start and .done callbacks that hold and release the\\nconntrack reference for the duration of the dump, and move the\\nnfct_help() call after the cb-\u003eargs[0] early-return check in the dump\\ncallback to avoid dereferencing ct-\u003eext unnecessarily.\\n\\n BUG: KASAN: slab-use-after-free in ctnetlink_exp_ct_dump_table+0x4f/0x2e0\\n Read of size 8 at addr ffff88810597ebf0 by task ctnetlink_poc/133\\n\\n CPU: 1 UID: 0 PID: 133 Comm: ctnetlink_poc Not tainted 7.0.0-rc2+ #3 PREEMPTLAZY\\n Call Trace:\\n  \u003cTASK\u003e\\n  ctnetlink_exp_ct_dump_table+0x4f/0x2e0\\n  netlink_dump+0x333/0x880\\n  netlink_recvmsg+0x3e2/0x4b0\\n  ?
