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-2026-89817 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-2026-89817/ (Markdown: https://insights.sbomify.com/CVE-2026-89817/index.md)","id":"CVE-2026-89817","markdown":"https://insights.sbomify.com/CVE-2026-89817/index.md","name":"CVE-2026-89817","record":{"aliases":["AZL-101306","BELL-CVE-2026-89817","DEBIAN-CVE-2026-89817","GHSA-g57w-mh9m-gp2m","UBUNTU-CVE-2026-89817"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel DRM","requires_auth":"none","summary":"A missing null termination in the Linux kernel DRM gud driver allows reading out-of-bounds memory or causing a crash when processing TV mode names from a USB device.","user_interaction":"not_required","vuln_class":"information_disclosure"},"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\ndrm/gud: NUL-terminate TV mode names read from the device\n\ngud_connector_add_tv_mode() reads a buffer of fixed-size mode names from\nthe USB device and passes pointers into it to\ndrm_mode_create_tv_properties_legacy(), which calls strlen() on each one.\nNothing guarantees the device NUL-terminates a name, so strlen() can run\npast the end of a slot and, for the last mode, past the end of the\nallocation.\n\nTerminate each name at the end of its slot before use.","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/gud: NUL-terminate TV mode names read from the device","id":"CVE-2026-89817","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":7,"next":{"headline":"drm/amdgpu/vcn: fix integer overflow in dec_msg buffer count check","id":"CVE-2026-89818"},"packages":[],"prev":{"headline":"drm: Fix drm_crtc_commit leak if signaled when PAGE_FLIP_EVENT is used","id":"CVE-2026-89816"},"products":["Linux"],"published":"2026-09-16","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":"2026-10-19","vendors":["Linux"]},"summary":"A missing null termination in the Linux kernel DRM gud driver allows reading out-of-bounds memory or causing a crash when processing TV mode names from a USB device.","url":"https://insights.sbomify.com/CVE-2026-89817/"}
