However,\nnot initializing all members may cause subtle issues, which are only\nexposed when CONFIG_INIT_STACK_ALL_PATTERN or CONFIG_INIT_STACK_NONE is\nenabled.\n\nadf4377_clk_register() fills in init.parent_data, and assumes that\ninit.parent_names is NULL.  However, the latter is uninitialized, and\nthus may cause a crash.\n\nSimilarly, adf4377_clk_register() fills in only parent_data.fw_name,\nleaving other members of the clk_parent_data structure uninitialized.\n\nMake sure all members are fully initialized, to fix such bugs, and to\navoid future breakage when converting drivers to a different method for\nspecifying the parents.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98667","source_modified_at":"2026-10-19T09:23:35.252Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"60e5448ddbec2dc206027a4850604d8fdf9973b7","lessThan":"6564f394a4a95fad534643a6ca0f1d36ff081799","status":"affected","versionType":"git"},{"version":"60e5448ddbec2dc206027a4850604d8fdf9973b7","lessThan":"e787fd23d5063c61582c3c27522240b6e6703fde","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98667","source_modified_at":"2026-10-19T09:23:35.252Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"7.0","status":"affected"},{"version":"0","lessThan":"7.0","status":"unaffected","versionType":"semver"},{"version":"7.2.10","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98667","source_modified_at":"2026-10-19T09:23:35.252Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"6564f394a4a95fad534643a6ca0f1d36ff081799","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00155,"percentile":0.04324,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:44:51.640Z","modified_at":"2026-10-19T09:23:35.252Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98667","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:23:35.252Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98667","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/6564f394a4a95fad534643a6ca0f1d36ff081799"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/e787fd23d5063c61582c3c27522240b6e6703fde"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T09:23:35.252Z","content_hash":"b87291fe6be4541860f2f98b9710f188fd9d656e7d8e43c78d9d5c080522490c"}}
