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-2025-71191 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2025-71191/ (Markdown: https://insights.sbomify.com/CVE-2025-71191/index.md)","id":"CVE-2025-71191","markdown":"https://insights.sbomify.com/CVE-2025-71191/index.md","name":"CVE-2025-71191","record":{"aliases":["BELL-CVE-2025-71191","DEBIAN-CVE-2025-71191","GHSA-4c95-wpmq-cc75","ROOT-OS-DEBIAN-11-CVE-2025-71191","ROOT-OS-DEBIAN-12-CVE-2025-71191","ROOT-OS-DEBIAN-13-CVE-2025-71191","ROOT-OS-UBUNTU-2204-CVE-2025-71191","ROOT-OS-UBUNTU-2404-CVE-2025-71191","UBUNTU-CVE-2025-71191"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel DMA driver","requires_auth":"low_privilege","summary":"A resource leak in the Linux kernel's at_hdmac DMA driver can lead to memory exhaustion and denial of service.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndmaengine: at_hdmac: fix device leak on of_dma_xlate()\n\nMake sure to drop the reference taken when looking up the DMA platform\ndevice during of_dma_xlate() when releasing channel resources.\n\nNote that commit 3832b78b3ec2 (\"dmaengine: at_hdmac: add missing\nput_device() call in at_dma_xlate()\") fixed the leak in a couple of\nerror paths but the reference is still leaking on successful allocation.","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":"dmaengine: at_hdmac: fix device leak on of_dma_xlate()","id":"CVE-2025-71191","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"other","year":"2025"},"n_packages":0,"n_references":7,"next":{"headline":"ALSA: ac97: fix a double free in snd_ac97_controller_register()","id":"CVE-2025-71192"},"packages":[],"prev":{"headline":"dmaengine: bcm-sba-raid: fix device leak on probe","id":"CVE-2025-71190"},"products":["Linux"],"published":"2026-01-31","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Linux"]},"summary":"A resource leak in the Linux kernel's at_hdmac DMA driver can lead to memory exhaustion and denial of service.","url":"https://insights.sbomify.com/CVE-2025-71191/"}
