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-2026-63900 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-2026-63900/ (Markdown: https://insights.sbomify.com/CVE-2026-63900/index.md)","id":"CVE-2026-63900","markdown":"https://insights.sbomify.com/CVE-2026-63900/index.md","name":"CVE-2026-63900","record":{"aliases":["BELL-CVE-2026-63900","DEBIAN-CVE-2026-63900","GHSA-46q2-6xm2-q797","ROOT-OS-UBUNTU-2204-CVE-2026-63900","UBUNTU-CVE-2026-63900"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel USB driver","requires_auth":"none","summary":"A missing sanity check in the Linux kernel Keyspan USB driver allows local attackers to read stale or uninitialized memory via crafted USB transfers.","user_interaction":"not_required","vuln_class":"information_disclosure"},"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: keyspan: fix missing indat transfer sanity check\n\nAdd the missing sanity check on the size of usa49wg indat transfers to\navoid parsing stale or uninitialised slab data.","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: keyspan: fix missing indat transfer sanity check","id":"CVE-2026-63900","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"USB: serial: digi_acceleport: fix memory corruption with small endpoints","id":"CVE-2026-63901"},"packages":[],"prev":{"headline":"USB: serial: mxuport: fix memory corruption with small endpoint","id":"CVE-2026-63899"},"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 missing sanity check in the Linux kernel Keyspan USB driver allows local attackers to read stale or uninitialized memory via crafted USB transfers.","url":"https://insights.sbomify.com/CVE-2026-63900/"}
