An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-54184 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2023-54184/ (Markdown: https://insights.sbomify.com/CVE-2023-54184/index.md)","id":"CVE-2023-54184","markdown":"https://insights.sbomify.com/CVE-2023-54184/index.md","name":"CVE-2023-54184","record":{"aliases":["BELL-CVE-2023-54184","DEBIAN-CVE-2023-54184","GHSA-mhc4-7fcr-wrj3","UBUNTU-CVE-2023-54184"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel iSCSI","requires_auth":"none","summary":"A use-after-free vulnerability in the Linux kernel iSCSI target allows attackers to cause a denial of service via a NULL pointer dereference.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: target: iscsit: Free cmds before session free\n\nCommands from recovery entries are freed after session has been closed.\nThat leads to use-after-free at command free or NPE with such call trace:\n\nTime2Retain timer expired for SID: 1, cleaning up iSCSI session.\nBUG: kernel NULL pointer dereference, address: 0000000000000140\nRIP: 0010:sbitmap_queue_clear+0x3a/0xa0\nCall Trace:\n target_release_cmd_kref+0xd1/0x1f0 [target_core_mod]\n transport_generic_free_cmd+0xd1/0x180 [target_core_mod]\n iscsit_free_cmd+0x53/0xd0 [iscsi_target_mod]\n iscsit_free_connection_recovery_entries+0x29d/0x320 [iscsi_target_mod]\n iscsit_close_session+0x13a/0x140 [iscsi_target_mod]\n iscsit_check_post_dataout+0x440/0x440 [iscsi_target_mod]\n call_timer_fn+0x24/0x140\n\nMove cleanup of recovery enrties to before session freeing.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"scsi: target: iscsit: Free cmds before session free","id":"CVE-2023-54184","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2023"},"n_packages":0,"n_references":6,"next":{"headline":"btrfs: remove BUG_ON()'s in add_new_free_space()","id":"CVE-2023-54185"},"packages":[],"prev":{"headline":"media: v4l2-core: Fix a potential resource leak in v4l2_fwnode_parse_link()","id":"CVE-2023-54183"},"products":["Linux"],"published":"2025-12-30","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel iSCSI target allows attackers to cause a denial of service via a NULL pointer dereference.","url":"https://insights.sbomify.com/CVE-2023-54184/"}
