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-2026-93104 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-2026-93104/ (Markdown: https://insights.sbomify.com/CVE-2026-93104/index.md)","id":"CVE-2026-93104","markdown":"https://insights.sbomify.com/CVE-2026-93104/index.md","name":"CVE-2026-93104","record":{"aliases":["AZL-102669","BELL-CVE-2026-93104","DEBIAN-CVE-2026-93104","GHSA-wqhx-qpfw-hj6x","UBUNTU-CVE-2026-93104"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel RDMA","requires_auth":"none","summary":"A use-after-free in the Linux kernel RDMA driver allows attackers to cause a denial of service or potentially execute code via port allocation failure.","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\nRDMA/rvt: Return NULL after port allocation failure\n\nrvt_alloc_device() deallocates the IB device when its port array cannot\nbe allocated but then returns the pointer to the released allocation.\nCallers treat any non-NULL value as valid and dereference it, resulting\nin a use-after-free.\n\nReturn NULL immediately after deallocation so callers can propagate the\nallocation failure.","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":"RDMA/rvt: Return NULL after port allocation failure","id":"CVE-2026-93104","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":"esp: do not unref managed frag pages in esp_ssg_unref()","id":"CVE-2026-93105"},"packages":[],"prev":{"headline":"RDMA/hfi1: Preserve unit 0 on allocation failure","id":"CVE-2026-93103"},"products":["Linux"],"published":"2026-09-17","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 use-after-free in the Linux kernel RDMA driver allows attackers to cause a denial of service or potentially execute code via port allocation failure.","url":"https://insights.sbomify.com/CVE-2026-93104/"}
