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-2026-80523 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-2026-80523/ (Markdown: https://insights.sbomify.com/CVE-2026-80523/index.md)","id":"CVE-2026-80523","markdown":"https://insights.sbomify.com/CVE-2026-80523/index.md","name":"CVE-2026-80523","record":{"aliases":["DEBIAN-CVE-2026-80523","GHSA-xwx3-g3pj-m9qw","UBUNTU-CVE-2026-80523"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A missing critical clock flag in the Spacemit K3 HDMA driver allows the clock to be disabled, causing the Linux system to hang during specific page faults.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nclk: spacemit: k3: set hdma clock as critical\n\nHDMA clock is responsible for the internal TCM access path of X100 RISC-V\ncore, so set the clock flag as critical to prevent it from being shut off,\notherwise the Linux system will hang, for example in the case of a vector\ninstruction access generates a page fault.","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":"clk: spacemit: k3: set hdma clock as critical","id":"CVE-2026-80523","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"optee: ffa: Add NULL check in optee_ffa_lend_protmem","id":"CVE-2026-80524"},"packages":[],"prev":{"headline":"crypto: tegra - fix rctx-\u003ecryptlen calculation in tegra_gcm_do_one_req()","id":"CVE-2026-80522"},"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 critical clock flag in the Spacemit K3 HDMA driver allows the clock to be disabled, causing the Linux system to hang during specific page faults.","url":"https://insights.sbomify.com/CVE-2026-80523/"}
