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-2026-90422/ (Markdown: https://insights.sbomify.com/CVE-2026-90422/index.md)","id":"CVE-2026-90422","markdown":"https://insights.sbomify.com/CVE-2026-90422/index.md","name":"CVE-2026-90422","record":{"aliases":["AZL-110438","BELL-CVE-2026-90422","DEBIAN-CVE-2026-90422","GHSA-hw67-72fp-vf5f","UBUNTU-CVE-2026-90422"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"unknown","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A memory leak in the MediaTek PLL clock driver error path can lead to resource exhaustion and denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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\nclk: mediatek: pllfh: Fix IO remapping leak in register_pllfhs error path\n\nWhen mtk_clk_register_pllfhs function fails to register a PLL, it\nunregisters all PLLs and cleans up itself in its error path before\nreturning, so the function callers don't need to do it.\n\nBut contrary to mtk_clk_unregister_pllfhs function, that does almost\nthe same sequence, it does not free the IO memory mapped on fhctl node,\nleading to a leak.\n\nFix this leak by factorizing the cleanup sequence in a new private\nfunction and use it both mtk_clk_register_pllfhs and\nmtk_clk_unregister_pllfhs functions.\n\nAlso, change the loop index start value to avoid the -1 operation on\nindex at each loop.","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":"clk: mediatek: pllfh: Fix IO remapping leak in register_pllfhs error path","id":"CVE-2026-90422","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"RDMA/rxe: Fix UAF in ODP init error-handling path","id":"CVE-2026-90423"},"packages":[],"prev":{"headline":"PCI: Fix UAF when probe runs concurrent to dyn ID removal","id":"CVE-2026-90421"},"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 memory leak in the MediaTek PLL clock driver error path can lead to resource exhaustion and denial of service.","url":"https://insights.sbomify.com/CVE-2026-90422/"}
