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-2023-53250 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-2023-53250/ (Markdown: https://insights.sbomify.com/CVE-2023-53250/index.md)","id":"CVE-2023-53250","markdown":"https://insights.sbomify.com/CVE-2023-53250/index.md","name":"CVE-2023-53250","record":{"aliases":["BELL-CVE-2023-53250","DEBIAN-CVE-2023-53250","GHSA-m84q-m2jg-26h3","ROOT-OS-DEBIAN-11-CVE-2023-53250","UBUNTU-CVE-2023-53250"],"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 null pointer dereference in the Linux kernel DMI sysfs driver causes a kernel panic, leading to denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"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-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nfirmware: dmi-sysfs: Fix null-ptr-deref in dmi_sysfs_register_handle\n\nKASAN reported a null-ptr-deref error:\n\nKASAN: null-ptr-deref in range [0x0000000000000008-0x000000000000000f]\nCPU: 0 PID: 1373 Comm: modprobe\nHardware name: QEMU Standard PC (i440FX + PIIX, 1996)\nRIP: 0010:dmi_sysfs_entry_release\n...\nCall Trace:\n \u003cTASK\u003e\n kobject_put\n dmi_sysfs_register_handle (drivers/firmware/dmi-sysfs.c:540) dmi_sysfs\n dmi_decode_table (drivers/firmware/dmi_scan.c:133)\n dmi_walk (drivers/firmware/dmi_scan.c:1115)\n dmi_sysfs_init (drivers/firmware/dmi-sysfs.c:149) dmi_sysfs\n do_one_initcall (init/main.c:1296)\n ...\nKernel panic - not syncing: Fatal exception\nKernel Offset: 0x4000000 from 0xffffffff81000000\n---[ end Kernel panic - not syncing: Fatal exception ]---\n\nIt is because previous patch added kobject_put() to release the memory\nwhich will call  dmi_sysfs_entry_release() and list_del().\n\nHowever, list_add_tail(entry-\u003elist) is called after the error block,\nso the list_head is uninitialized and cannot be deleted.\n\nMove error handling to after list_add_tail to fix this.","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":"firmware: dmi-sysfs: Fix null-ptr-deref in dmi_sysfs_register_handle","id":"CVE-2023-53250","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"null_dereference","year":"2023"},"n_packages":0,"n_references":4,"next":{"headline":"wifi: iwlwifi: pcie: fix NULL pointer dereference in iwl_pcie_irq_rx_msix_handler()","id":"CVE-2023-53251"},"packages":[],"prev":{"headline":"clk: imx: clk-imx8mn: fix memory leak in imx8mn_clocks_probe","id":"CVE-2023-53249"},"products":["Linux"],"published":"2025-09-15","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":"2026-05-23","vendors":["Linux"]},"summary":"A null pointer dereference in the Linux kernel DMI sysfs driver causes a kernel panic, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2023-53250/"}
