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-2026-80582 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-2026-80582/ (Markdown: https://insights.sbomify.com/CVE-2026-80582/index.md)","id":"CVE-2026-80582","markdown":"https://insights.sbomify.com/CVE-2026-80582/index.md","name":"CVE-2026-80582","record":{"aliases":["DEBIAN-CVE-2026-80582","GHSA-8m43-m8xf-jm3h","UBUNTU-CVE-2026-80582"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel DRM","requires_auth":"low_privilege","summary":"A missing boundary check in the Linux kernel DRM shmem helper allows installing invalid PMD mappings, potentially causing system crashes or privilege escalation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/shmem_helper: Check VMA boundaries for PMD mappings\n\nIn the -\u003ehuge_fault handler do not install a PMD huge page\nmapping if the huge page exceeds the boundaries of the VMA.\n\nAll other -\u003ehuge_fault handlers have similar checks and the\nresulting mapping will trigger a VM_BUG_ON_VMA() if it ever\nreaches copy_pmd_range().","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":"drm/shmem_helper: Check VMA boundaries for PMD mappings","id":"CVE-2026-80582","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"ASoC: codecs: lpass-tx-macro: Fix enum kcontrol accesses","id":"CVE-2026-80583"},"packages":[],"prev":{"headline":"ASoC: SOF: ipc4-pcm: Continue the pipeline trigger in case of IPC timeout","id":"CVE-2026-80581"},"products":["Linux"],"published":"2026-08-26","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-27","vendors":["Linux"]},"summary":"A missing boundary check in the Linux kernel DRM shmem helper allows installing invalid PMD mappings, potentially causing system crashes or privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-80582/"}
