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-2026-23763 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-2026-23763/ (Markdown: https://insights.sbomify.com/CVE-2026-23763/index.md)","id":"CVE-2026-23763","markdown":"https://insights.sbomify.com/CVE-2026-23763/index.md","name":"CVE-2026-23763","record":{"aliases":["GHSA-3hvj-ch28-p4x7"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows audio driver","requires_auth":"low_privilege","summary":"Local attackers can exploit a kernel memory exposure flaw in VB-Audio drivers to read/write kernel memory and escalate privileges to SYSTEM.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-668","name":"Exposure of Resource to Wrong Sphere"}],"description":"VB-Audio Matrix and Matrix Coconut (versions ending in 1.0.2.2 and 2.0.2.2 and earlier, respectively), contain a local privilege escalation vulnerability in the VBMatrix VAIO virtual audio driver (vbmatrixvaio64*_win10.sys). The driver allocates a 128-byte non-paged pool buffer and, upon receiving IOCTL 0x222060, maps it into user space using an MDL and MmMapLockedPagesSpecifyCache. Because the allocation size is not page-aligned, the mapping exposes the entire 0x1000-byte kernel page containing the buffer plus adjacent non-paged pool allocations with read/write permissions. An unprivileged local attacker can open a device handle (using the required 0x800 attribute flag), invoke the IOCTL to obtain the mapping, and then read or modify live kernel objects and pointers present on that page. This enables bypass of KASLR, arbitrary kernel memory read/write within the exposed page, corruption of kernel objects, and escalation to SYSTEM.","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 Matrix Drivers Local Privilege Escalation via Kernel Memory Exposure","id":"CVE-2026-23763","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"VB-Audio Voicemeeter \u0026 Matrix Drivers DoS via Corrupted IoAllocateMdl Length","id":"CVE-2026-23764"},"packages":[],"prev":{"headline":"VB-Audio Voicemeeter \u0026 Matrix Drivers DoS via MmMapLockedPagesSpecifyCache","id":"CVE-2026-23762"},"products":["Matrix","Matrix Coconut"],"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":"total"},"state":"PUBLISHED","updated":"2026-05-14","vendors":["VB-Audio Software"]},"summary":"Local attackers can exploit a kernel memory exposure flaw in VB-Audio drivers to read/write kernel memory and escalate privileges to SYSTEM.","url":"https://insights.sbomify.com/CVE-2026-23763/"}
