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-2026-80679 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-2026-80679/ (Markdown: https://insights.sbomify.com/CVE-2026-80679/index.md)","id":"CVE-2026-80679","markdown":"https://insights.sbomify.com/CVE-2026-80679/index.md","name":"CVE-2026-80679","record":{"aliases":["AZL-98156","BELL-CVE-2026-80679","DEBIAN-CVE-2026-80679","GHSA-68wp-mw9w-2vpr","UBUNTU-CVE-2026-80679"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A NULL pointer dereference in the Linux kernel s390/dasd driver can cause a system crash, requiring a kernel patch.","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\ns390/dasd: Fix potential NULL pointer dereference\n\ndasd_release_space() checks the implementation of the is_ese()\ndiscipline function before calling it to determine if a given device is\nan ESE DASD.\n\nThe current usage of the logical AND operator will lead to a NULL\npointer dereference as the function is called even if the function\npointer is NULL.\n\nFix this by using the logical OR operator.","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":"s390/dasd: Fix potential NULL pointer dereference","id":"CVE-2026-80679","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"i2c: amd-mp2: Unregister callback on adapter add failure","id":"CVE-2026-80680"},"packages":[],"prev":{"headline":"i2c: imx: Fix slave registration race and error handling","id":"CVE-2026-80678"},"products":["Linux"],"published":"2026-08-28","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":"2026-08-28","vendors":["Linux"]},"summary":"A NULL pointer dereference in the Linux kernel s390/dasd driver can cause a system crash, requiring a kernel patch.","url":"https://insights.sbomify.com/CVE-2026-80679/"}
