It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-53022 in the wild and no public exploit code.\n\nAffected product: Linux kernel. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2023-53022/ (Markdown: https://insights.sbomify.com/CVE-2023-53022/index.md)","id":"CVE-2023-53022","markdown":"https://insights.sbomify.com/CVE-2023-53022/index.md","name":"CVE-2023-53022","record":{"aliases":["BELL-CVE-2023-53022","DEBIAN-CVE-2023-53022","GHSA-9933-f4m5-7v96","UBUNTU-CVE-2023-53022"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel network driver","requires_auth":"low_privilege","summary":"A deadlock in the enetc network driver can cause a system hang, requiring a kernel patch to resolve.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-667","name":"Improper Locking"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: enetc: avoid deadlock in enetc_tx_onestep_tstamp()\n\nThis lockdep splat says it better than I could:\n\n================================\nWARNING: inconsistent lock state\n6.2.0-rc2-07010-ga9b9500ffaac-dirty #967 Not tainted\n--------------------------------\ninconsistent {IN-SOFTIRQ-W} -\u003e {SOFTIRQ-ON-W} usage.\nkworker/1:3/179 [HC0[0]:SC0[0]:HE1:SE1] takes:\nffff3ec4036ce098 (_xmit_ETHER#2){+.?.}-{3:3}, at: netif_freeze_queues+0x5c/0xc0\n{IN-SOFTIRQ-W} state was registered at:\n  _raw_spin_lock+0x5c/0xc0\n  sch_direct_xmit+0x148/0x37c\n  __dev_queue_xmit+0x528/0x111c\n  ip6_finish_output2+0x5ec/0xb7c\n  ip6_finish_output+0x240/0x3f0\n  ip6_output+0x78/0x360\n  ndisc_send_skb+0x33c/0x85c\n  ndisc_send_rs+0x54/0x12c\n  addrconf_rs_timer+0x154/0x260\n  call_timer_fn+0xb8/0x3a0\n  __run_timers.part.0+0x214/0x26c\n  run_timer_softirq+0x3c/0x74\n  __do_softirq+0x14c/0x5d8\n  ____do_softirq+0x10/0x20\n  call_on_irq_stack+0x2c/0x5c\n  do_softirq_own_stack+0x1c/0x30\n  __irq_exit_rcu+0x168/0x1a0\n  irq_exit_rcu+0x10/0x40\n  el1_interrupt+0x38/0x64\nirq event stamp: 7825\nhardirqs last  enabled at (7825): [\u003cffffdf1f7200cae4\u003e] exit_to_kernel_mode+0x34/0x130\nhardirqs last disabled at (7823): [\u003cffffdf1f708105f0\u003e] __do_softirq+0x550/0x5d8\nsoftirqs last  enabled at (7824): [\u003cffffdf1f7081050c\u003e] __do_softirq+0x46c/0x5d8\nsoftirqs last disabled at (7811): [\u003cffffdf1f708166e0\u003e] ____do_softirq+0x10/0x20\n\nother info that might help us debug this:\n Possible unsafe locking scenario:\n\n       CPU0\n       ----\n  lock(_xmit_ETHER#2);\n  \u003cInterrupt\u003e\n    lock(_xmit_ETHER#2);\n\n *** DEADLOCK ***\n\n3 locks held by kworker/1:3/179:\n #0: ffff3ec400004748 ((wq_completion)events){+.+.}-{0:0}, at: process_one_work+0x1f4/0x6c0\n #1: ffff80000a0bbdc8 ((work_completion)(\u0026priv-\u003etx_onestep_tstamp)){+.+.}-{0:0}, at: process_one_work+0x1f4/0x6c0\n #2: ffff3ec4036cd438 (\u0026dev-\u003etx_global_lock){+.+.}-{3:3}, at: netif_tx_lock+0x1c/0x34\n\nWorkqueue: events enetc_tx_onestep_tstamp\nCall trace:\n print_usage_bug.part.0+0x208/0x22c\n mark_lock+0x7f0/0x8b0\n __lock_acquire+0x7c4/0x1ce0\n lock_acquire.part.0+0xe0/0x220\n lock_acquire+0x68/0x84\n _raw_spin_lock+0x5c/0xc0\n netif_freeze_queues+0x5c/0xc0\n netif_tx_lock+0x24/0x34\n enetc_tx_onestep_tstamp+0x20/0x100\n process_one_work+0x28c/0x6c0\n worker_thread+0x74/0x450\n kthread+0x118/0x11c\n\nbut I'll say it anyway: the enetc_tx_onestep_tstamp() work item runs in\nprocess context, therefore with softirqs enabled (i.o.w., it can be\ninterrupted by a softirq).
