An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-33824 in the wild since at least 18 Aug 2026.\n\nAffected product: Microsoft Windows 10 1607. 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-2026-33824/ (Markdown: https://insights.sbomify.com/CVE-2026-33824/index.md)","id":"CVE-2026-33824","markdown":"https://insights.sbomify.com/CVE-2026-33824/index.md","name":"CVE-2026-33824","record":{"aliases":["GHSA-q6qf-3m2m-xq4f"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows IKE Service","requires_auth":"none","summary":"An unauthorized attacker can execute code over the network via a double free vulnerability in the Windows IKE Service Extensions.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_10_1607","vendor":"microsoft"},{"product":"windows_10_1809","vendor":"microsoft"},{"product":"windows_10_21h2","vendor":"microsoft"},{"product":"windows_10_22h2","vendor":"microsoft"},{"product":"windows_11_23h2","vendor":"microsoft"},{"product":"windows_11_24h2","vendor":"microsoft"},{"product":"windows_11_25h2","vendor":"microsoft"},{"product":"windows_11_26h1","vendor":"microsoft"},{"product":"windows_server_2016","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"},{"product":"windows_server_2022","vendor":"microsoft"},{"product":"windows_server_2022_23h2","vendor":"microsoft"},{"product":"windows_server_2025","vendor":"microsoft"}],"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-415","name":"Double Free"}],"description":"Double free in Windows IKE Extension allows an unauthorized attacker to execute code over a network.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-04-21","github_poc":2,"max_poc_stars":7,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-05-18T13:44:31Z","kind":"github_poc","ref":"https://github.com/EpSiLoNPoInTOrI/IKEV2-POC","stars":7,"title":"IKEv2, ikeext.dll, CVE-2026-33824, double free, heap grooming, ROP, SKF fragmentation, Windows exploit, anti-debug, obfuscation, API hooking, shellcode, reverse shell"},{"date":"2026-04-21T15:29:56Z","kind":"github_poc","ref":"https://github.com/kaleth4/CVE-2026-33824","stars":2,"title":null}],"tier":"exploited"},"has_fix":null,"headline":"Microsoft Internet Key Exchange (IKE) Service Extensions Double Free","id":"CVE-2026-33824","indexable":true,"kev":{"dateAdded":"2026-08-18","dueDate":"2026-08-21","knownRansomwareCampaignUse":"Unknown","product":"Internet Key Exchange (IKE) Service Extensions","requiredAction":"Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes).
