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-2026-74501/ (Markdown: https://insights.sbomify.com/CVE-2026-74501/index.md)","id":"CVE-2026-74501","markdown":"https://insights.sbomify.com/CVE-2026-74501/index.md","name":"CVE-2026-74501","record":{"aliases":["AZL-96105","BELL-CVE-2026-74501","DEBIAN-CVE-2026-74501","GHSA-jc2g-jx97-4cg9","UBUNTU-CVE-2026-74501"],"analysis":null,"analysis_generated_by":null,"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-audio: fix use-after-free in ump_to_endpoint()\n\ncreate_midi2_ump() registers a card-owned snd_ump_endpoint and stores a\nback-pointer to its per-interface snd_usb_midi2_ump object in\nump-\u003eprivate_data, but it never installs an ump-\u003eprivate_free hook and\nnever clears that pointer.\n\nIf a later step of snd_usb_midi_v2_create() fails, its error path calls\nfree_all_midi2_umps(), which kfree()s the snd_usb_midi2_ump object while\nthe already-registered endpoint keeps pointing at it.
