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-2026-23426 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-2026-23426/ (Markdown: https://insights.sbomify.com/CVE-2026-23426/index.md)","id":"CVE-2026-23426","markdown":"https://insights.sbomify.com/CVE-2026-23426/index.md","name":"CVE-2026-23426","record":{"aliases":["BELL-CVE-2026-23426","DEBIAN-CVE-2026-23426","GHSA-6ww2-mmfj-6f5p","ROOT-OS-DEBIAN-12-CVE-2026-23426","ROOT-OS-DEBIAN-13-CVE-2026-23426","ROOT-OS-UBUNTU-2404-CVE-2026-23426","UBUNTU-CVE-2026-23426"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel DRM driver","requires_auth":"low_privilege","summary":"A reference leak in the Linux kernel's LogicVC DRM driver can lead to resource exhaustion and potential denial of service.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/logicvc: Fix device node reference leak in logicvc_drm_config_parse()\n\nThe logicvc_drm_config_parse() function calls of_get_child_by_name() to\nfind the \"layers\" node but fails to release the reference, leading to a\ndevice node reference leak.\n\nFix this by using the __free(device_node) cleanup attribute to automatic\nrelease the reference when the variable goes out of scope.","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":"drm/logicvc: Fix device node reference leak in logicvc_drm_config_parse()","id":"CVE-2026-23426","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"other","year":"2026"},"n_packages":0,"n_references":6,"next":{"headline":"ksmbd: fix use-after-free in durable v2 replay of active file handles","id":"CVE-2026-23427"},"packages":[],"prev":{"headline":"KVM: arm64: Fix ID register initialization for non-protected pKVM guests","id":"CVE-2026-23425"},"products":["Linux"],"published":"2026-04-03","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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A reference leak in the Linux kernel's LogicVC DRM driver can lead to resource exhaustion and potential denial of service.","url":"https://insights.sbomify.com/CVE-2026-23426/"}
