An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-105016 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- Microsoft.Native.Quic.MsQuic.Schannel (NuGet): affected from 2.5.11-ci.156755675; fixed in 2.5.11-ci.159417053\n- Microsoft.Native.Quic.MsQuic.Schannel (NuGet): affected from 2.5.11-ci.156755675; fixed in 2.5.11-ci.159417053\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-2026-105016/ (Markdown: https://insights.sbomify.com/CVE-2026-105016/index.md)","id":"CVE-2026-105016","markdown":"https://insights.sbomify.com/CVE-2026-105016/index.md","name":"CVE-2026-105016","record":{"aliases":["GHSA-5gjq-3f94-rcf7","UBUNTU-CVE-2026-105016"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft QUIC","requires_auth":"none","summary":"Heap-based buffer overflow in Microsoft QUIC allows remote attackers to execute arbitrary code without authentication.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"Heap-based buffer overflow in Microsoft QUIC allows an unauthorized attacker to execute code over a network.","ecosystems":["NuGet"],"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":"Microsoft QUIC Remote Code Execution Vulnerability","id":"CVE-2026-105016","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"UVdesk support-center-bundle before 1.1.3.3 IDOR via rateTicket Ticket Rating Endpoint","id":"CVE-2026-105029"},"packages":[{"ecosystem":"NuGet","fixed":["2.5.11-ci.159417053"],"introduced":["2.5.11-ci.156755675"],"last_affected":[],"package":"Microsoft.Native.Quic.MsQuic.Schannel","purl":null,"source":"GHSA-5gjq-3f94-rcf7"},{"ecosystem":"NuGet","fixed":["2.5.11-ci.159417053"],"introduced":["2.5.11-ci.156755675"],"last_affected":[],"package":"Microsoft.Native.Quic.MsQuic.Schannel","purl":"pkg:nuget/Microsoft.Native.Quic.MsQuic.Schannel","source":"GHSA-5gjq-3f94-rcf7"}],"prev":{"headline":"Azure Pipelines Remote Code Execution Vulnerability","id":"CVE-2026-105014"},"products":[".NET 10.0 runtime",".NET 11.0 runtime",".NET 8.0 runtime",".NET 9.0 runtime","Microsoft Visual Studio 2022 version 17.14","Microsoft Visual Studio 2026 version 18.10","Windows 11 Version 23H2","Windows 11 Version 24H2","Windows 11 Version 25H2","Windows 11 Version 26H2","Windows 11 version 23H2","Windows 11 version 26H1","Windows Server 2022","Windows Server 2025","Windows Server 2025 (Server Core installation)"],"published":"2026-10-13","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-29","vendors":["Microsoft"]},"summary":"Heap-based buffer overflow in Microsoft QUIC allows remote attackers to execute arbitrary code without authentication.","url":"https://insights.sbomify.com/CVE-2026-105016/"}
