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-2026-64333 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2026-64333/ (Markdown: https://insights.sbomify.com/CVE-2026-64333/index.md)","id":"CVE-2026-64333","markdown":"https://insights.sbomify.com/CVE-2026-64333/index.md","name":"CVE-2026-64333","record":{"aliases":["BELL-CVE-2026-64333","DEBIAN-CVE-2026-64333","GHSA-92hp-m55f-9hjw","ROOT-OS-DEBIAN-12-CVE-2026-64333","ROOT-OS-UBUNTU-2204-CVE-2026-64333","UBUNTU-CVE-2026-64333"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel USB driver","requires_auth":"low_privilege","summary":"A memory corruption vulnerability in the Linux kernel's digi_acceleport USB driver allows attackers to corrupt write buffers, potentially leading to code execution or system crashes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nUSB: serial: digi_acceleport: fix write buffer corruption\n\nThe digi_write_inb_command() is supposed to wait for the write urb to\nbecome available or return an error, but instead it updates the transfer\nbuffer and tries to resubmit the urb on timeout.\n\nTo make things worse, for commands like break control where no timeout\nis used, the driver would corrupt the urb immediately due to a broken\njiffies comparison (on 32-bit machines this takes five minutes of uptime\nto trigger due to INITIAL_JIFFIES).\n\nFix this by adding the missing return on timeout and waiting\nindefinitely when no timeout has been specified as intended.\n\nThis issue was (sort of) flagged by Sashiko when reviewing an unrelated\nchange to the driver.","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: digi_acceleport: fix write buffer corruption","id":"CVE-2026-64333","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"USB: serial: digi_acceleport: fix hard lockup on disconnect","id":"CVE-2026-64334"},"packages":[],"prev":{"headline":"USB: ulpi: fix memory leak on registration failure","id":"CVE-2026-64332"},"products":["Linux"],"published":"2026-07-25","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"A memory corruption vulnerability in the Linux kernel's digi_acceleport USB driver allows attackers to corrupt write buffers, potentially leading to code execution or system crashes.","url":"https://insights.sbomify.com/CVE-2026-64333/"}
