It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-23761 exists.\n\nAffected product: VB-Audio Software Matrix. 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-2026-23761/ (Markdown: https://insights.sbomify.com/CVE-2026-23761/index.md)","id":"CVE-2026-23761","markdown":"https://insights.sbomify.com/CVE-2026-23761/index.md","name":"CVE-2026-23761","record":{"aliases":["GHSA-6hwp-64jx-rmg2"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows audio drivers","requires_auth":"none","summary":"Local unprivileged users can crash Windows systems via a null dereference in VB-Audio virtual audio drivers.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-824","name":"Access of Uninitialized Pointer"}],"description":"VB-Audio Voicemeeter, Voicemeeter Banana, and Voicemeeter Potato (versions ending in 1.1.1.9, 2.1.1.9, and 3.1.1.9 and earlier, respectively), as well as VB-Audio Matrix and Matrix Coconut (versions ending in 1.0.2.2 and 2.0.2.2 and earlier, respectively), contain a vulnerability in their virtual audio drivers (vbvoicemeetervaio64*.sys, vbmatrixvaio64*.sys, vbaudio_vmauxvaio*.sys, vbaudio_vmvaio*.sys, and vbaudio_vmvaio3*.sys). When a handle is opened with a special file attribute value, the drivers improperly initialize FILE_OBJECT-\u003eFsContext to a non-pointer magic value. If subsequent operations are not handled by the VB-Audio driver and are forwarded down the audio driver stack (e.g., via PortCls to ks.sys), the invalid FsContext value can be dereferenced, causing a kernel crash (BSoD), typically SYSTEM_SERVICE_EXCEPTION with STATUS_ACCESS_VIOLATION. This flaw allows a local unprivileged user to trigger a denial-of-service on affected Windows systems.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"VB-Audio Voicemeeter \u0026 Matrix Drivers DoS via Improper FILE_OBJECT FsContext Initialization","id":"CVE-2026-23761","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"VB-Audio Voicemeeter \u0026 Matrix Drivers DoS via MmMapLockedPagesSpecifyCache","id":"CVE-2026-23762"},"packages":[],"prev":{"headline":"SmarterTools SmarterMail Authentication Bypass Using an Alternate Path or Channel","id":"CVE-2026-23760"},"products":["Matrix","Matrix Coconut","Voicemeeter (Standard)","Voicemeeter Banana","Voicemeeter Potato"],"published":"2026-01-22","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-14","vendors":["VB-Audio Software"]},"summary":"Local unprivileged users can crash Windows systems via a null dereference in VB-Audio virtual audio drivers.","url":"https://insights.sbomify.com/CVE-2026-23761/"}
