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-2026-98755 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-2026-98755/ (Markdown: https://insights.sbomify.com/CVE-2026-98755/index.md)","id":"CVE-2026-98755","markdown":"https://insights.sbomify.com/CVE-2026-98755/index.md","name":"CVE-2026-98755","record":{"aliases":["AZL-108725","BELL-CVE-2026-98755","DEBIAN-CVE-2026-98755","GHSA-g66w-7p4m-7w28","UBUNTU-CVE-2026-98755"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"An attacker with local access can read uninitialized kernel stack data via the VCC driver, potentially exposing sensitive information.","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\ntty: vcc: zero-initialize control packet in vcc_send_ctl()\n\nThe stack-allocated struct vio_vcc pkt was partially initialized,\nleaving the tag.stype_env field uninitialized before being sent via\nldc_write(), potentially leaking kernel stack data to the LDC peer.","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":"tty: vcc: zero-initialize control packet in vcc_send_ctl()","id":"CVE-2026-98755","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: cdns3: Fix NULL pointer dereference in cdns3_pci_probe","id":"CVE-2026-98756"},"packages":[],"prev":{"headline":"tty: vcc: hold port lock when clearing tty pointer in vcc_cleanup","id":"CVE-2026-98754"},"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":"2026-10-26","vendors":["Linux"]},"summary":"An attacker with local access can read uninitialized kernel stack data via the VCC driver, potentially exposing sensitive information.","url":"https://insights.sbomify.com/CVE-2026-98755/"}
