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-2026-63963 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-2026-63963/ (Markdown: https://insights.sbomify.com/CVE-2026-63963/index.md)","id":"CVE-2026-63963","markdown":"https://insights.sbomify.com/CVE-2026-63963/index.md","name":"CVE-2026-63963","record":{"aliases":["BELL-CVE-2026-63963","DEBIAN-CVE-2026-63963","GHSA-p527-vfp9-6cmq","ROOT-OS-DEBIAN-11-CVE-2026-63963","ROOT-OS-DEBIAN-12-CVE-2026-63963","ROOT-OS-UBUNTU-2204-CVE-2026-63963","UBUNTU-CVE-2026-63963"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel USB","requires_auth":"none","summary":"A malicious USB device can trigger an out-of-bounds read in the Linux kernel TCPM driver, potentially leaking sensitive memory data to the attacker.","user_interaction":"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: typec: tcpm: validate VDO count in Discover Identity ACK handlers\n\nProperly validate the count passed from a device when calling\nsvdm_consume_identity() or svdm_consume_identity_sop_prime() as the\ndevice-controlled value could index off of the static arrays, which\ncould leak 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: typec: tcpm: validate VDO count in Discover Identity ACK handlers","id":"CVE-2026-63963","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"usb: typec: ucsi: ccg: reject firmware images without a ':' record header","id":"CVE-2026-63964"},"packages":[],"prev":{"headline":"usb: typec: tcpm: bound altmode_desc[] per iteration in svdm_consume_modes()","id":"CVE-2026-63962"},"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":"2026-10-21","vendors":["Linux"]},"summary":"A malicious USB device can trigger an out-of-bounds read in the Linux kernel TCPM driver, potentially leaking sensitive memory data to the attacker.","url":"https://insights.sbomify.com/CVE-2026-63963/"}
