An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-74279 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-2026-74279/ (Markdown: https://insights.sbomify.com/CVE-2026-74279/index.md)","id":"CVE-2026-74279","markdown":"https://insights.sbomify.com/CVE-2026-74279/index.md","name":"CVE-2026-74279","record":{"aliases":["BELL-CVE-2026-74279","DEBIAN-CVE-2026-74279","GHSA-4p2p-ww9m-h8rq","UBUNTU-CVE-2026-74279"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel crypto driver","requires_auth":"none","summary":"A logic error in the Cavium CPT crypto driver causes DMA buffer leaks and repeated unmapping, potentially leading to resource exhaustion or denial of service.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: cavium/cpt - fix DMA cleanup using wrong loop index\n\nThe sg_cleanup error path used list[i] instead of list[j] when unmapping\nDMA buffers, leaking successfully mapped entries and repeatedly unmapping\nthe failed one.","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":"crypto: cavium/cpt - fix DMA cleanup using wrong loop index","id":"CVE-2026-74279","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"crypto: marvell/octeontx - fix DMA cleanup using wrong loop index","id":"CVE-2026-74280"},"packages":[],"prev":{"headline":"ALSA: seq: Fix kernel heap address leak in bounce_error_event()","id":"CVE-2026-74278"},"products":["Linux"],"published":"2026-08-15","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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-16","vendors":["Linux"]},"summary":"A logic error in the Cavium CPT crypto driver causes DMA buffer leaks and repeated unmapping, potentially leading to resource exhaustion or denial of service.","url":"https://insights.sbomify.com/CVE-2026-74279/"}
