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  ? aa_sk_perm+0x184/0x450\n  sock_recvmsg+0xde/0xf0\n\n Allocated by task 133:\n  kmem_cache_alloc_noprof+0x134/0x440\n  __nf_conntrack_alloc+0xa8/0x2b0\n  ctnetlink_create_conntrack+0xa1/0x900\n  ctnetlink_new_conntrack+0x3cf/0x7d0\n  nfnetlink_rcv_msg+0x48e/0x510\n  netlink_rcv_skb+0xc9/0x1f0\n  nfnetlink_rcv+0xdb/0x220\n  netlink_unicast+0x3ec/0x590\n  netlink_sendmsg+0x397/0x690\n  __sys_sendmsg+0xf4/0x180\n\n Freed by task 0:\n  slab_free_after_rcu_debug+0xad/0x1e0\n  rcu_core+0x5c3/0x9c0"

A freed kernel object can plausibly be reclaimed and shaped for information disclosure, so confidentiality impact is high.\\nI:H - Use-after-free in kernel heap memory can plausibly be leveraged beyond a crash into memory corruption or control-flow manipulation. Following the required conservative scoring, integrity impact is high.\\nA:H - The reported failure is a KASAN slab-use-after-free in kernel netlink dump handling and can cause an oops or panic. The attacker can trigger it repeatedly through local netlink requests.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"e844a928431fa8f1359d1f4f2cef53d9b446bf52\", \"lessThan\": \"d8cd0efbccc5cfb0a80da744a7da76e1333ab925\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"e844a928431fa8f1359d1f4f2cef53d9b446bf52\", \"lessThan\": \"9821b47f669eb82791fa0b1a6ebaf9aa219bea72\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"e844a928431fa8f1359d1f4f2cef53d9b446bf52\", \"lessThan\": \"bdf2724eefd4455a66863abb025bab8d3aa98c57\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"e844a928431fa8f1359d1f4f2cef53d9b446bf52\", \"lessThan\": \"f04cc86d59906513d2d62183b882966fc0ae0390\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"e844a928431fa8f1359d1f4f2cef53d9b446bf52\", \"lessThan\": \"f025171feef2ac65663d7986f1d5ff0c28d6b2a9\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"e844a928431fa8f1359d1f4f2cef53d9b446bf52\", \"lessThan\": \"04c8907ce4e3d3e26c5e1a3e47aa5d17082cbb56\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"e844a928431fa8f1359d1f4f2cef53d9b446bf52\", \"lessThan\": \"cd541f15b60e2257441398cf495d978f816d09f8\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"e844a928431fa8f1359d1f4f2cef53d9b446bf52\", \"lessThan\": \"5cb81eeda909dbb2def209dd10636b51549a3f8a\", \"versionType\": \"git\"}], \"programFiles\": [\"net/netfilter/nf_conntrack_netlink.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"3.10\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"3.10\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.10.253\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.15.203\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.167\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.130\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.78\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.20\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"6.19.10\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.19.*\"}, {\"status\": \"unaffected\", \"version\": \"7.0\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"net/netfilter/nf_conntrack_netlink.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/d8cd0efbccc5cfb0a80da744a7da76e1333ab925\"}, {\"url\": \"https://git.kernel.org/stable/c/9821b47f669eb82791fa0b1a6ebaf9aa219bea72\"}, {\"url\": \"https://git.kernel.org/stable/c/bdf2724eefd4455a66863abb025bab8d3aa98c57\"}, {\"url\": \"https://git.kernel.org/stable/c/f04cc86d59906513d2d62183b882966fc0ae0390\"}, {\"url\": \"https://git.kernel.org/stable/c/f025171feef2ac65663d7986f1d5ff0c28d6b2a9\"}, {\"url\": \"https://git.kernel.org/stable/c/04c8907ce4e3d3e26c5e1a3e47aa5d17082cbb56\"}, {\"url\": \"https://git.kernel.org/stable/c/cd541f15b60e2257441398cf495d978f816d09f8\"}, {\"url\": \"https://git.kernel.org/stable/c/5cb81eeda909dbb2def209dd10636b51549a3f8a\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nnetfilter: ctnetlink: fix use-after-free in ctnetlink_dump_exp_ct()\\n\\nctnetlink_dump_exp_ct() stores a conntrack pointer in cb-\u003edata for the\\nnetlink dump callback ctnetlink_exp_ct_dump_table(), but drops the\\nconntrack reference immediately after netlink_dump_start().
