If setting the rate fails, it attempts to\ndisable and unprepare a clock that was never enabled. This issue was\nspotted while reviewing \"rust: clk: add devres-managed clks\" [1].\n\nRegister the cleanup action only after successfully preparing and enabling\nthe clock.\n\n[1]: https://lore.kernel.org/rust-for-linux/20260706-clk-type-state-v5-3-67c5f326a16c@collabora.com","modified":"2026-09-19T03:47:24.803809545Z","published":"2026-09-17T16:06:42.342Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90147.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0d4d262c1664365e17e0a5ba2ab79f4db484b44e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/647157fecb42b72d930e7b7d0bfbc5f2db9a858a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9a365f41fe0f227ef5a269e240233bd0bffc66c9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9d4843f1051259854f724e9cdc5b9eac56327037"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90147.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90147"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"9934a1bd45b2b03f6d1204a6ae2780d3b009799f"},{"fixed":"9a365f41fe0f227ef5a269e240233bd0bffc66c9"},{"fixed":"9d4843f1051259854f724e9cdc5b9eac56327037"},{"fixed":"647157fecb42b72d930e7b7d0bfbc5f2db9a858a"},{"fixed":"0d4d262c1664365e17e0a5ba2ab79f4db484b44e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90147.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.12.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90147.json"}}],"schema_version":"1.9.0"}
