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-2026-72432 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-2026-72432/ (Markdown: https://insights.sbomify.com/CVE-2026-72432/index.md)","id":"CVE-2026-72432","markdown":"https://insights.sbomify.com/CVE-2026-72432/index.md","name":"CVE-2026-72432","record":{"aliases":["DEBIAN-CVE-2026-72432","GHSA-qp72-j2rc-w8mc","UBUNTU-CVE-2026-72432"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel TPM driver","requires_auth":"none","summary":"A missing NULL check in the Linux kernel TPM CRB driver allows local attackers to trigger a system crash via device matching overrides.","user_interaction":"not_required","vuln_class":"null_dereference"},"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_crb: Check ACPI_COMPANION() against NULL during probe\n\nEvery platform driver can be forced to match a device that doesn't match\nits list of device IDs because of device_match_driver_override(), so\nplatform drivers that rely on the existence of a device's ACPI companion\nobject need to verify its presence.\n\nAccordingly, add a requisite ACPI_COMPANION() check against NULL to the\ntpm_crb driver.","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":"tpm_crb: Check ACPI_COMPANION() against NULL during probe","id":"CVE-2026-72432","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"netfilter: nft_meta_bridge: fix NFT_META_BRI_IIFPVID stack leak","id":"CVE-2026-72433"},"packages":[],"prev":{"headline":"alloc_tag: fix use-after-free in /proc/allocinfo after module unload","id":"CVE-2026-72431"},"products":["Linux"],"published":"2026-08-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-17","vendors":["Linux"]},"summary":"A missing NULL check in the Linux kernel TPM CRB driver allows local attackers to trigger a system crash via device matching overrides.","url":"https://insights.sbomify.com/CVE-2026-72432/"}
