It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-85769 in the wild and no public exploit code.\n\nAffected product: Red Hat Enterprise Linux 10. 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-2026-85769/ (Markdown: https://insights.sbomify.com/CVE-2026-85769/index.md)","id":"CVE-2026-85769","markdown":"https://insights.sbomify.com/CVE-2026-85769/index.md","name":"CVE-2026-85769","record":{"aliases":["AZL-99918","DEBIAN-CVE-2026-85769","GHSA-8pv5-2vvh-f478","SUSE-SU-2026:23878-1","SUSE-SU-2026:23926-1","SUSE-SU-2026:4363-1","UBUNTU-CVE-2026-85769","openSUSE-SU-2026:11836-1"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"TPM emulation library","requires_auth":"none","summary":"A heap out-of-bounds read in libtpms allows attackers to crash the TPM emulation process via malformed state blobs, causing denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"A flaw was found in libtpms, a library that provides software TPM 2.0 emulation. When restoring TPM 2.0 state (for example during a virtual machine's power-on or state/migration restore), a malformed state blob can supply an oversized skip-block length that is not validated against the remaining size of the input buffer. This can drive an internal size counter negative, which bypasses a subsequent bounds check due to an unsafe signed-to-unsigned conversion, causing the parser to read memory outside the bounds of the heap buffer holding the state data. Successful exploitation can crash the process hosting libtpms (such as swtpm), resulting in a denial of service of the emulated TPM device and the virtual machine that depends on it. No data corruption or information disclosure was confirmed.","ecosystems":["SUSE:Linux Enterprise Module for Server Applications 15 SP7","SUSE:Linux Micro 6.0","SUSE:Linux Micro 6.1","openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":"2026-09-04","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-09-04T18:05:49Z","kind":"github_poc","ref":"https://github.com/isukasanuj/CVE-2026-85769","stars":0,"title":"Heap out-of-bounds read in libtpms TPM 2.0 state deserialization — CVE-2026-85769"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Libtpms: libtpms: heap out-of-bounds read in tpm2 state unmarshalling via unchecked block_skip_read() blocksize","id":"CVE-2026-85769","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":4,"n_references":5,"next":{"headline":"Unverified access point ownership in Amazon EFS CSI Driver","id":"CVE-2026-85781"},"packages":[{"ecosystem":"SUSE:Linux Enterprise Module for Server Applications 15 SP7","fixed":["0.9.6-150600.3.6.1"],"introduced":["0"],"last_affected":[],"package":"libtpms","purl":"pkg:rpm/suse/libtpms\u0026distro=SUSE%20Linux%20Enterprise%20Module%20for%20Server%20Applications%2015%20SP7","source":"SUSE-SU-2026:4363-1"},{"ecosystem":"SUSE:Linux Micro 6.0","fixed":["0.9.6-3.1"],"introduced":["0"],"last_affected":[],"package":"libtpms","purl":"pkg:rpm/suse/libtpms\u0026distro=SUSE%20Linux%20Micro%206.0","source":"SUSE-SU-2026:23878-1"},{"ecosystem":"SUSE:Linux Micro 6.1","fixed":["0.9.6-slfo.1.1_3.1"],"introduced":["0"],"last_affected":[],"package":"libtpms","purl":"pkg:rpm/suse/libtpms\u0026distro=SUSE%20Linux%20Micro%206.1","source":"SUSE-SU-2026:23926-1"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["0.10.2-2.1"],"introduced":["0"],"last_affected":[],"package":"libtpms","purl":"pkg:rpm/opensuse/libtpms\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2026:11836-1"}],"prev":{"headline":"SSH.NET: ScpClient allows server-side RCE via default SCP path handling","id":"CVE-2026-85756"},"products":["Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 9"],"published":"2026-09-04","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"SUSE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-09","vendors":["Red Hat"]},"summary":"A heap out-of-bounds read in libtpms allows attackers to crash the TPM emulation process via malformed state blobs, causing denial of service.","url":"https://insights.sbomify.com/CVE-2026-85769/"}
