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-2026-90120 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-2026-90120/ (Markdown: https://insights.sbomify.com/CVE-2026-90120/index.md)","id":"CVE-2026-90120","markdown":"https://insights.sbomify.com/CVE-2026-90120/index.md","name":"CVE-2026-90120","record":{"aliases":["DEBIAN-CVE-2026-90120","GHSA-rfj6-7g8r-3866","UBUNTU-CVE-2026-90120"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A missing return value check in the Linux kernel GICv5 driver allows out-of-bounds memory corruption, potentially enabling code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/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\nirqchip/gic-v5: Check get_logical_index() return value in MADT IAFFID parsing\n\nIn gic_acpi_parse_iaffid() a given MADT GICC entry might not correspond\nto a logical cpu recognized by the kernel, resulting in the cpu variable\ninitialization to an error value.\n\nCurrently, the get_logical_index() return value is not checked for failure,\nwhich might result in out-of-bounds memory corruption while trying to\nindex a per_cpu variable array.\n\nAdd a check to evaluate get_logical_index() return value.","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":"irqchip/gic-v5: Check get_logical_index() return value in MADT IAFFID parsing","id":"CVE-2026-90120","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"irqchip/gic-v5: Clear per-CPU IRS data on teardown","id":"CVE-2026-90121"},"packages":[],"prev":{"headline":"ALSA: ice1712: Fix the card leak at probe error with the auto-cleanup","id":"CVE-2026-90119"},"products":["Linux"],"published":"2026-09-17","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"A missing return value check in the Linux kernel GICv5 driver allows out-of-bounds memory corruption, potentially enabling code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-90120/"}
