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-2025-68792 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2025-68792/ (Markdown: https://insights.sbomify.com/CVE-2025-68792/index.md)","id":"CVE-2025-68792","markdown":"https://insights.sbomify.com/CVE-2025-68792/index.md","name":"CVE-2025-68792","record":{"aliases":["BELL-CVE-2025-68792","DEBIAN-CVE-2025-68792","GHSA-2wfq-pvgx-w5wx","UBUNTU-CVE-2025-68792"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel TPM","requires_auth":"low_privilege","summary":"An out-of-bounds indexing flaw in the Linux kernel TPM2 sessions allows attackers to cause memory corruption, potentially leading to code execution or system crashes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ntpm2-sessions: Fix out of range indexing in name_size\n\n'name_size' does not have any range checks, and it just directly indexes\nwith TPM_ALG_ID, which could lead into memory corruption at worst.\n\nAddress the issue by only processing known values and returning -EINVAL for\nunrecognized values.\n\nMake also 'tpm_buf_append_name' and 'tpm_buf_fill_hmac_session' fallible so\nthat errors are detected before causing any spurious TPM traffic.\n\nEnd also the authorization session on failure in both of the functions, as\nthe session state would be then by definition corrupted.","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":"tpm2-sessions: Fix out of range indexing in name_size","id":"CVE-2025-68792","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"drm/amdgpu: fix a job-\u003epasid access race in gpu recovery","id":"CVE-2025-68793"},"packages":[],"prev":{"headline":"fuse: missing copy_finish in fuse-over-io-uring argument copies","id":"CVE-2025-68791"},"products":["Linux"],"published":"2026-01-13","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"An out-of-bounds indexing flaw in the Linux kernel TPM2 sessions allows attackers to cause memory corruption, potentially leading to code execution or system crashes.","url":"https://insights.sbomify.com/CVE-2025-68792/"}
