No remote message can cause the required namespace teardown.\nAC:L - The attacker controls both sides of the race: worker threads repeatedly create and close topology subscriptions while their process exits the network namespace, racing `rwork`/`swork` and socket callbacks against `tipc_topsrv_stop()`. No victim or hardware state is required.\nPR:L - `tipc_sk_create()`, `tipc_connect()`, and `tipc_conn_rcv_sub()` have no capability or authentication gate; an ordinary user can obtain the `CAP_SYS_ADMIN` needed for `CLONE_NEWNET` inside a new user namespace. No init-namespace privilege is required.\nUI:N - The attacker creates the namespaces, opens and floods `TIPC_TOP_SRV` connections, closes them, and exits to start `cleanup_net()` without any victim action.\nS:U - The freed `tipc_conn` and workqueue objects belong to the host kernel, and exploitation of `tipc_topsrv_stop()` affects that same kernel authority without crossing a VM, IOMMU, or other security boundary.\nC:H - `tipc_conn_kref_release()` frees `con` while teardown retains its address; `tipc_conn_close()` then reads `con->sock->sk` and follows reclaimed subscription and socket pointers. Reclaiming this object permits attacker-controlled pointer dereferences usable as kernel-memory read primitives.\nI:H - After the free, `tipc_conn_close()` modifies reclaimed `con->flags`, writes through `sk->sk_user_data`, processes reclaimed subscription lists, and calls `kernel_sock_shutdown()` through `con->sock->ops`. These provide memory-write and control-flow primitives.\nA:H - The reported race produced a page fault in `tipc_conn_close()`, `queue_work()` on a destroyed receive workqueue, and an RCU stall in `tipc_topsrv_exit_net()`; these paths can oops, panic, or wedge the system."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["net/tipc/topsrv.c"], "versions": [{"version": "c5fa7b3cf3cb22e4ac60485fc2dc187fe012910f", "lessThan": "09dbd610f78aaed65d7b379c270ce4090a8151ac", "status": "affected", "versionType": "git"}, {"version": "c5fa7b3cf3cb22e4ac60485fc2dc187fe012910f", "lessThan": "21622e5ae8b232c2e64eb1adf5546cf078d2987d", "status": "affected", "versionType": "git"}, {"version": "c5fa7b3cf3cb22e4ac60485fc2dc187fe012910f", "lessThan": "7167afaaaee37191f8b6afa0c91e0fef41460705", "status": "affected", "versionType": "git"}, {"version": "c5fa7b3cf3cb22e4ac60485fc2dc187fe012910f", "lessThan": "7f796bb3b440d7f1b14c0e3b520462eb34f553af", "status": "affected", "versionType": "git"}, {"version": "c5fa7b3cf3cb22e4ac60485fc2dc187fe012910f", "lessThan": "da9c16568bc79140a54c1f5fcf07a0305df47b37", "status": "affected", "versionType": "git"}, {"version": "c5fa7b3cf3cb22e4ac60485fc2dc187fe012910f", "lessThan": "0af8780bdfdfc91fb9127bddb9c48fab67dc9d9e", "status": "affected", "versionType": "git"}, {"version": "c5fa7b3cf3cb22e4ac60485fc2dc187fe012910f", "lessThan": "fb717c536af2aafeca520ff11d1e0f25f7ab8fa9", "status": "affected", "versionType": "git"}, {"version": "c5fa7b3cf3cb22e4ac60485fc2dc187fe012910f", "lessThan": "3acdd44385bc7e2e57605e073691ce69cc5a960d", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["net/tipc/topsrv.c"], "versions": [{"version": "3.11", "status": "affected"}, {"version": "0", "lessThan": "3.11", "status": "unaffected", "versionType": "semver"}, {"version": "5.10.273", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver"}, {"version": "5.15.224", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.191", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.160", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.113", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.57", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2.11", "lessThanOrEqual": "7.2.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.3", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.11", "versionEndExcluding": "5.10.273"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.11", "versionEndExcluding": "5.15.224"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.11", "versionEndExcluding": "6.1.191"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.11", "versionEndExcluding": "6.6.160"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.11", "versionEndExcluding": "6.12.113"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.11", "versionEndExcluding": "6.18.57"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.11", "versionEndExcluding": "7.2.11"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.11", "versionEndExcluding": "7.3"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/09dbd610f78aaed65d7b379c270ce4090a8151ac"}, {"url": "https://git.kernel.org/stable/c/21622e5ae8b232c2e64eb1adf5546cf078d2987d"}, {"url": "https://git.kernel.org/stable/c/7167afaaaee37191f8b6afa0c91e0fef41460705"}, {"url": "https://git.kernel.org/stable/c/7f796bb3b440d7f1b14c0e3b520462eb34f553af"}, {"url": "https://git.kernel.org/stable/c/da9c16568bc79140a54c1f5fcf07a0305df47b37"}, {"url": "https://git.kernel.org/stable/c/0af8780bdfdfc91fb9127bddb9c48fab67dc9d9e"}, {"url": "https://git.kernel.org/stable/c/fb717c536af2aafeca520ff11d1e0f25f7ab8fa9"}, {"url": "https://git.kernel.org/stable/c/3acdd44385bc7e2e57605e073691ce69cc5a960d"}], "title": "tipc: destroy topsrv workqueues before closing connections", "x_generator": {"engine": "bippy-1.2.0"}}}}
