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-2026-45752 in the wild and no public exploit code.\n\nAffected product: Oisf Suricata. 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-2026-45752/ (Markdown: https://insights.sbomify.com/CVE-2026-45752/index.md)","id":"CVE-2026-45752","markdown":"https://insights.sbomify.com/CVE-2026-45752/index.md","name":"CVE-2026-45752","record":{"aliases":["DEBIAN-CVE-2026-45752","GHSA-qmc9-vqq2-8mv3","UBUNTU-CVE-2026-45752"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Network IDS/IPS engine","requires_auth":"none","summary":"A use-after-free in Suricata's decompress transforms allows attackers to cause a denial of service via malicious rules.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"suricata","vendor":"oisf"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Starting in version 8.0.0 and prior to version 8.0.5, when certain detection transforms are chained, the decompress transform pipeline could read from an inspection buffer after it had been reallocated and freed. The issue is reached during network traffic processing, but requires a malicious rule as Suricata will crash whatever the traffic. Version 8.0.5 contains a fix. As a workaround, avoid rules that chain `gunzip` or `zlib_deflate` with `max-size` bigger than 4096 after another transform.","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":"Suricata detect/transform: use-after-free in decompress transforms","id":"CVE-2026-45752","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"oisf:suricata","products":["oisf:suricata"],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Symfony's HtmlSanitizer UrlAttributeSanitizer Omits action/formaction/poster/cite — `javascript`: URI Survives Sanitization (XSS)","id":"CVE-2026-45753"},"packages":[],"prev":{"headline":"Suricata detect/transform: use-after-free in dotprefix transform","id":"CVE-2026-45751"},"products":["suricata"],"published":"2026-09-10","related":[{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2023-35853","kev_date_added":null,"published":"2023-06-19"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2021-37592","kev_date_added":null,"published":"2021-11-19"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2018-10244","kev_date_added":null,"published":"2019-04-04"},{"cvss_score":9.4,"headline":"Memory corruption in Suricata","id":"CVE-2026-94083","kev_date_added":null,"published":"2026-09-20"},{"cvss_score":9.4,"headline":"Use after free in Suricata","id":"CVE-2026-94084","kev_date_added":null,"published":"2026-09-20"},{"cvss_score":9.1,"headline":"Suricata http2: protocol-change type confusion can lead to denial of service","id":"CVE-2026-45764","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":8.2,"headline":"Suricata smtp/mime: heap out-of-bounds read quoted-printable decoder","id":"CVE-2026-57228","kev_date_added":null,"published":"2026-09-18"}],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-11","vendors":["OISF"]},"summary":"A use-after-free in Suricata's decompress transforms allows attackers to cause a denial of service via malicious rules.","url":"https://insights.sbomify.com/CVE-2026-45752/"}
