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-2026-63928 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-2026-63928/ (Markdown: https://insights.sbomify.com/CVE-2026-63928/index.md)","id":"CVE-2026-63928","markdown":"https://insights.sbomify.com/CVE-2026-63928/index.md","name":"CVE-2026-63928","record":{"aliases":["BELL-CVE-2026-63928","DEBIAN-CVE-2026-63928","GHSA-mmp6-qmxw-fp3c","ROOT-OS-UBUNTU-2204-CVE-2026-63928","UBUNTU-CVE-2026-63928"],"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 driver","requires_auth":"none","summary":"A malicious USB device can trigger memory corruption in the Linux kernel's omninet driver, potentially allowing local attackers to execute code or escalate privileges.","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: serial: omninet: fix memory corruption with small endpoint\n\nMake sure that the bulk-out buffers are at least as large as the\nhardcoded transfer size to avoid user-controlled slab corruption should\na malicious device report a smaller endpoint max packet size than\nexpected.","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: serial: omninet: fix memory corruption with small endpoint","id":"CVE-2026-63928","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"iio: buffer: Fix DMA fence leak in iio_buffer_enqueue_dmabuf()","id":"CVE-2026-63929"},"packages":[],"prev":{"headline":"usb: dwc2: Fix use after free in debug code","id":"CVE-2026-63927"},"products":["Linux"],"published":"2026-07-19","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":"2026-07-19","vendors":["Linux"]},"summary":"A malicious USB device can trigger memory corruption in the Linux kernel's omninet driver, potentially allowing local attackers to execute code or escalate privileges.","url":"https://insights.sbomify.com/CVE-2026-63928/"}
