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-2026-90319 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-2026-90319/ (Markdown: https://insights.sbomify.com/CVE-2026-90319/index.md)","id":"CVE-2026-90319","markdown":"https://insights.sbomify.com/CVE-2026-90319/index.md","name":"CVE-2026-90319","record":{"aliases":["AZL-101879","BELL-CVE-2026-90319","DEBIAN-CVE-2026-90319","GHSA-2x23-jxch-r563","UBUNTU-CVE-2026-90319"],"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","requires_auth":"none","summary":"A use-after-free vulnerability in the Linux kernel RapidIO subsystem allows local attackers to cause a denial of service or potentially execute code via dangling pointer dereference.","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\nrapidio: clear mport-\u003enet when rio_add_net() fails\n\nrio_alloc_net() stores the newly allocated rio_net in mport-\u003enet before\nrio_scan_alloc_net() registers the device.\n\nIf rio_add_net() fails, rio_scan_alloc_net() drops the device reference\nwith put_device(), which releases the rio_net through the device release\ncallback.
