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-2026-98772 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-2026-98772/ (Markdown: https://insights.sbomify.com/CVE-2026-98772/index.md)","id":"CVE-2026-98772","markdown":"https://insights.sbomify.com/CVE-2026-98772/index.md","name":"CVE-2026-98772","record":{"aliases":["AZL-108776","BELL-CVE-2026-98772","DEBIAN-CVE-2026-98772","GHSA-39q3-pw49-mrvf","UBUNTU-CVE-2026-98772"],"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 serial","requires_auth":"none","summary":"A race condition in Linux kernel USB serial drivers allows attackers to trigger a use-after-free, potentially leading to code execution or system crashes.","user_interaction":"not_required","vuln_class":"use_after_free"},"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: fix port tear down use-after-free\n\nSome drivers for multiport devices access port driver data from\ncompletion handlers of shared URBs submitted at attach() or first open()\nand stopped at disconnect() or last close(), respectively.\n\nA simple NULL check before accessing the driver data makes sure that a\nport state container has at least been allocated, but a completion\nhandler can still race with port tear down.\n\nReorder the disconnect handling so that ports are not deregistered (and\ntheir driver data freed) until after all ports have been hung up and the\ndriver disconnect() callback has run so that all I/O has been stopped.","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: fix port tear down use-after-free","id":"CVE-2026-98772","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"USB: cdc-acm: skip URB restart in port_shutdown if disconnected","id":"CVE-2026-98773"},"packages":[],"prev":{"headline":"usb: storage: sierra_ms: reject short SWoC info transfers","id":"CVE-2026-98771"},"products":["Linux"],"published":"2026-10-18","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 race condition in Linux kernel USB serial drivers allows attackers to trigger a use-after-free, potentially leading to code execution or system crashes.","url":"https://insights.sbomify.com/CVE-2026-98772/"}
