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-2026-63961 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-2026-63961/ (Markdown: https://insights.sbomify.com/CVE-2026-63961/index.md)","id":"CVE-2026-63961","markdown":"https://insights.sbomify.com/CVE-2026-63961/index.md","name":"CVE-2026-63961","record":{"aliases":["AZL-92783","BELL-CVE-2026-63961","DEBIAN-CVE-2026-63961","GHSA-m857-r6wp-m3gv","ROOT-OS-UBUNTU-2204-CVE-2026-63961","UBUNTU-CVE-2026-63961"],"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 malicious USB device can trigger uninitialized stack data disclosure in the Linux kernel DisplayPort altmode driver.","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: altmodes/displayport: validate count before reading Status Update VDO\n\nA broken/malicious device can send the incorrect count for a status\nupdate VDO, which will cause the kernel to read uninitialized stack data\nand send it off elsewhere.\n\nFix this up by correctly verifying the count for the update object.","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: altmodes/displayport: validate count before reading Status Update VDO","id":"CVE-2026-63961","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: typec: tcpm: bound altmode_desc[] per iteration in svdm_consume_modes()","id":"CVE-2026-63962"},"packages":[],"prev":{"headline":"usb: typec: wcove: don't write past struct pd_message in wcove_read_rx_buffer()","id":"CVE-2026-63960"},"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":"2026-07-20","vendors":["Linux"]},"summary":"A malicious USB device can trigger uninitialized stack data disclosure in the Linux kernel DisplayPort altmode driver.","url":"https://insights.sbomify.com/CVE-2026-63961/"}
