It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-98769 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-2026-98769/ (Markdown: https://insights.sbomify.com/CVE-2026-98769/index.md)","id":"CVE-2026-98769","markdown":"https://insights.sbomify.com/CVE-2026-98769/index.md","name":"CVE-2026-98769","record":{"aliases":["AZL-108996","BELL-CVE-2026-98769","DEBIAN-CVE-2026-98769","GHSA-m6wv-vgq8-7pqj","UBUNTU-CVE-2026-98769"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel USB gadget","requires_auth":"none","summary":"A malicious USB host can trigger out-of-bounds memory access in the Linux kernel USB audio gadget driver, potentially leading to code execution or privilege escalation.","user_interaction":"required","vuln_class":"memory_corruption"},"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\nusb: gadget: f_uac1_legacy: validate bRequest index in generic_{set,get}_cmd\n\ngeneric_set_cmd() and generic_get_cmd() use the low nibble of\nctrl-\u003ebRequest as an index into con-\u003edata[]:\n\n    u8 cmd = (ctrl-\u003ebRequest \u0026 0x0F);  /* 0 .. 15 */\n    ...\n    con-\u003edata[cmd] = value;            /* OOB when cmd \u003e= 5 */\n\nstruct usb_audio_control (include/linux/usb/audio.h) declares data as\na 5-element array, so indices 5 through 15 write (or read) up to 44\nbytes past the end of the array on the heap.\n\nA malicious USB host can craft a class-specific SET_CUR / GET_CUR\nrequest with an arbitrary bRequest value, triggering the out-of-bounds\naccess from an IRQ completion handler with no further preconditions.\n\nAdd an ARRAY_SIZE() guard to both functions.","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":"usb: gadget: f_uac1_legacy: validate bRequest index in generic_{set,get}_cmd","id":"CVE-2026-98769","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"usb: gadget: midi2: Fix the jack descriptor array sizes","id":"CVE-2026-98770"},"packages":[],"prev":{"headline":"usb: typec: anx7411 - stop the IRQ before destroying the workqueue","id":"CVE-2026-98768"},"products":["Linux"],"published":"2026-10-18","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":"2026-10-21","vendors":["Linux"]},"summary":"A malicious USB host can trigger out-of-bounds memory access in the Linux kernel USB audio gadget driver, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-98769/"}
