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-2026-74676 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-2026-74676/ (Markdown: https://insights.sbomify.com/CVE-2026-74676/index.md)","id":"CVE-2026-74676","markdown":"https://insights.sbomify.com/CVE-2026-74676/index.md","name":"CVE-2026-74676","record":{"aliases":["AZL-97221","BELL-CVE-2026-74676","DEBIAN-CVE-2026-74676","GHSA-r6h8-mfh3-gh59","UBUNTU-CVE-2026-74676"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A local attacker can bypass authorization checks to modify keyboard meta mode on non-controlling consoles via the KDSKBMETA ioctl.","user_interaction":"not_required","vuln_class":"missing_authorization"},"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\nvt: add permission check for KDSKBMETA ioctl\n\nKDSKBMETA modifies keyboard meta mode but lacks the !perm check that all\nother keyboard setter ioctls in vt_k_ioctl() enforce, allowing a process\nto change meta mode on a non-controlling console without authorization.","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":"vt: add permission check for KDSKBMETA ioctl","id":"CVE-2026-74676","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"net: usb: ipheth: fix carrier_work UAF on disconnect","id":"CVE-2026-74677"},"packages":[],"prev":{"headline":"vt: stabilize tty reference in kbd_keycode with tty_port_tty_get","id":"CVE-2026-74675"},"products":["Linux"],"published":"2026-08-22","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":"2026-08-25","vendors":["Linux"]},"summary":"A local attacker can bypass authorization checks to modify keyboard meta mode on non-controlling consoles via the KDSKBMETA ioctl.","url":"https://insights.sbomify.com/CVE-2026-74676/"}
