An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-89861 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-2026-89861/ (Markdown: https://insights.sbomify.com/CVE-2026-89861/index.md)","id":"CVE-2026-89861","markdown":"https://insights.sbomify.com/CVE-2026-89861/index.md","name":"CVE-2026-89861","record":{"aliases":["AZL-101339","BELL-CVE-2026-89861","DEBIAN-CVE-2026-89861","GHSA-jp2p-cx4h-xhw3","UBUNTU-CVE-2026-89861"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A use-after-free in the qla2xxx SCSI driver allows attackers to execute arbitrary code or escalate privileges via concurrent vport deallocation.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Hold vport reference in qla24xx_report_id_acquisition()\n\nIn the format 1 path, the virtual port is located on ha-\u003evp_list while\nholding vport_slock, but the lock is dropped before vp is used:\nqla_update_host_map() is called and VP_IDX_ACQUIRED/REGISTER_FC4_NEEDED/\nREGISTER_FDMI_NEEDED are set on vp.
