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-2026-98728 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-2026-98728/ (Markdown: https://insights.sbomify.com/CVE-2026-98728/index.md)","id":"CVE-2026-98728","markdown":"https://insights.sbomify.com/CVE-2026-98728/index.md","name":"CVE-2026-98728","record":{"aliases":["BELL-CVE-2026-98728","DEBIAN-CVE-2026-98728","GHSA-m4p2-cqr5-x7cx","UBUNTU-CVE-2026-98728"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel TPM driver","requires_auth":"none","summary":"A local attacker can read stale kernel memory via a truncated TPM response, potentially leaking sensitive data.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ntpm: fix off-by-four bounds check in tpm2_get_random()\n\nWhen the response carries the TPM2_ST_SESSIONS tag, tpm2_get_random()\nskips the 4-byte parameter size field before locating the random data,\nbut the bounds check still validates the response length against\nTPM_HEADER_SIZE.
