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-2023-52989 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-2023-52989/ (Markdown: https://insights.sbomify.com/CVE-2023-52989/index.md)","id":"CVE-2023-52989","markdown":"https://insights.sbomify.com/CVE-2023-52989/index.md","name":"CVE-2023-52989","record":{"aliases":["BELL-CVE-2023-52989","DEBIAN-CVE-2023-52989","GHSA-x768-g2cv-hv4j","UBUNTU-CVE-2023-52989"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A memory leak in the Linux kernel FireWire subsystem allows attackers to cause denial of service by exhausting kernel memory.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nfirewire: fix memory leak for payload of request subaction to IEC 61883-1 FCP region\n\nThis patch is fix for Linux kernel v2.6.33 or later.\n\nFor request subaction to IEC 61883-1 FCP region, Linux FireWire subsystem\nhave had an issue of use-after-free. The subsystem allows multiple\nuser space listeners to the region, while data of the payload was likely\nreleased before the listeners execute read(2) to access to it for copying\nto user space.\n\nThe issue was fixed by a commit 281e20323ab7 (\"firewire: core: fix\nuse-after-free regression in FCP handler\"). The object of payload is\nduplicated in kernel space for each listener. When the listener executes\nioctl(2) with FW_CDEV_IOC_SEND_RESPONSE request, the object is going to\nbe released.\n\nHowever, it causes memory leak since the commit relies on call of\nrelease_request() in drivers/firewire/core-cdev.c. Against the\nexpectation, the function is never called due to the design of\nrelease_client_resource(). The function delegates release task\nto caller when called with non-NULL fourth argument. The implementation\nof ioctl_send_response() is the case. It should release the object\nexplicitly.\n\nThis commit fixes the bug.","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":"firewire: fix memory leak for payload of request subaction to IEC 61883-1 FCP region","id":"CVE-2023-52989","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":7,"next":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.","id":"CVE-2023-52990"},"packages":[],"prev":{"headline":"ALSA: hda/via: Avoid potential array out-of-bound in add_secret_dac_path()","id":"CVE-2023-52988"},"products":["Linux"],"published":"2025-03-27","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A memory leak in the Linux kernel FireWire subsystem allows attackers to cause denial of service by exhausting kernel memory.","url":"https://insights.sbomify.com/CVE-2023-52989/"}
