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-2026-74642 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-2026-74642/ (Markdown: https://insights.sbomify.com/CVE-2026-74642/index.md)","id":"CVE-2026-74642","markdown":"https://insights.sbomify.com/CVE-2026-74642/index.md","name":"CVE-2026-74642","record":{"aliases":["BELL-CVE-2026-74642","DEBIAN-CVE-2026-74642","GHSA-r4jc-x475-grgg","UBUNTU-CVE-2026-74642"],"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","requires_auth":"none","summary":"A use-after-free vulnerability in the Linux kernel's ALSA USB MIDI2 driver allows local attackers to execute arbitrary code or escalate privileges.","user_interaction":"not_required","vuln_class":"use_after_free"},"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\nALSA: usb: Fix UAF at delayed release of MIDI2 EPs\n\nThe recent fix for UAF in ump_to_endpoint() caused another UAF because\nit tries to dereference the UMP endpoint object, but this might be\nexecuted at a delayed context where the endpoint has been already\nreleased.\n\nAdd private_free to clear the associated data for avoiding the further\ndereference for delayed releases.","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":"ALSA: usb: Fix UAF at delayed release of MIDI2 EPs","id":"CVE-2026-74642","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"samples/damon/mtier: error out for zero quota goal target values","id":"CVE-2026-74643"},"packages":[],"prev":{"headline":"ALSA: usx2y: bound the hwdep mmap fault offset","id":"CVE-2026-74641"},"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":"2026-08-22","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel's ALSA USB MIDI2 driver allows local attackers to execute arbitrary code or escalate privileges.","url":"https://insights.sbomify.com/CVE-2026-74642/"}
